LASER COMMUNICATION SYSTEM
(Light Amplification by Stimulated Emission of Radiation)

Abstract:
Laser communication is one of the key areas in wireless Communications. They work only under clear line-of-sight conditions between each unit, but they eliminate the need for securing right of ways, buried cable installations and no government licensing is necessary. Free space laser communications systems can be quickly deployed since they are small and do not need any radio interference calculations. Additionally, no spectrum fees have to be paid. This paper includes analysis, optimization, design and system level development of signal transformation between satellites or any two sources. Which work similarly to fibre optic links, except the beam is transmitted through free space. The carrier used for the transmission signal is typically generated by a laser diode. Two parallel beams are needed, one for transmission and one for reception.

INTRUDUCTION:
Laser Communication is one of the emerging areas of wireless communication system. Due to its low noise ratio makes its one of the well suited communication medium for exchange of information. Currently laser commutation is adopted in satellite communication for space research activities and due to its efficiency on low noise ratio, inexpensive, low power and its flexibility and its resistance to the radio interferences makes laser communication as one of research area in wireless communication. In this process, this paper comprises the one such application of laser communication for information exchange between any two devices. In Laser Communication the transmitter and receiver must require a line-of-sight conditions and Laser communications systems have the benefit of eliminating the need for broadcast rights and buried cables. The carrier used for the transmission signal is typically generated by a laser…...

Laser

...LASERS IN PREPROSTHETIC SURGERY LASER is an acronym for light amplification of stimulated emission of radiation. Laser application in maxillofacial surgery practice covers control of leukoplakia, oral malignancy, preprosthetic or periodontal surgery, temporomandibular joint, uvulopalatostomy, and cosmetic procedures. Clinical lasers are of two types; soft lasers are essentially an aid to healing with relatively few rigorous studies available to support their use. Surgical hard lasers, however, can cut both hard and soft tissues and replace the scalpel and drill in many areas. From initial experiments with the ruby laser most clinicians are using argon, CO2 and now Nd:YAG systems. Both the CO2 and Nd:YAG lasers can be used for intraoral soft tissue surgeries. The advantages of lasers include a relatively bloodless surgical and postsurgical course, minimal swelling and scarring, coagulation, vaporization, and cutting, minimal or no suturing, reduction in surgical time, and, in a majority of cases, much less or no postsurgical pain. CO2 LASER Since its development in the early 1960s, the CO2 laser has been rapidly introduced into medical research and almost every dental and medical surgical specialty. In dental surgery it is mainly used for oral soft tissue applications. High-power lasers are one of the greatest technologies advances in dentistry field. In 1989 the first laser specifically designed for use in dentistry, a carbon dioxide (CO2) laser was introduced. The...

I would also like acknowledge my friends who helped me a lot in the completion f this and were always there at one call. JAGDEEP SINGH INTRODUCTION The name LASER is an acronym for Light Amplification by the Stimulated Emission of Radiation. Light is really an electromagnetic wave. Each wave has brightness and color, and vibrates at a certain angle, so-called polarization. This is also true for laser light but it is more parallel than any other light source. Every part of the beam has (almost) the exact same direction and the beam will therefore diverge very little. With a good laser an object at a distance of 1 km (0.6 mile) can be illuminated with a dot about 60 mm (2.3 inches) in radius. As it is so parallel it can also be focused to very...

Laser Printing Process

...Laser Printing Process This post will be talking about the six steps in the laser printing process, this is good for technicians who fix or repair printers along with a good learning experience. With my limited knowledge of printers I used this process to at least help diagnose the problem. If you have no idea how a printer works, I would not try to fix it. People have become hurt with these machines leave it to the professionals.   Step 1: Cleaning When an image has been deposited on the paper and the drum has separated from the paper, any remaining toner must be removed from the drum. A printer may have a blade that scrapes all excess toner from the drum. Some printers use an AC voltage on a wire that removes the charge from the drum surface and allows the excess toner to fall away from the drum. The excess toner is stored in a used toner container that may be emptied or discarded. Step 2: Conditioning This step involves removing the old latent image from the drum and conditioning the drum for a new latent image. Conditioning is done by placing a special wire, grid, or roller that receives a negative charge of about – 600 volts DC uniformly across the surface of the drum. The charged wire or grid is called the primary corona. The roller is called a conditioning roller. Step 3: Writing The writing process involves scanning the photosensitive drum with the laser beam. Every part of the drum that is exposed to the light has the surface charge reduced to about – 100...

Laser Ignition System

...ASME Internal Combustion Engine Division 2005 Fall Technical Conference: ARES-ARICE Symposium on Gas Fired Reciprocating Engines September 11 – 14 ,2005, Ottawa, Canada ICEF2005-1352 Laser Ignition - a New Concept to Use and Increase the Potentials of Gas Engines Dr. Günther Herdin/GEJenbacher GmbH & Co OHG Prof. Ernst Wintner/Technical University of Vienna DI Johann Klausner/GEJenbacher GmbH & Co OHG Josef Graf/Technical University of Vienna DI Martin Weinrotter/Technical University of Vienna Kurt Iskra/Technical University of Graz ABSTRACT Due to market demands aimed at increasing the efficiency and the power density of gas engines, existing ignition systems are rapidly approaching their limits. To avoid this, gas engine manufacturers are seeking new technologies. From the viewpoint of gas engine R&D engineers, ignition of the fuel/air mixture by means of a laser has great potential. Especially the thermodynamic requirements of a high compression ratio and a high power density are fulfilled well by laser ignition. Results of measurements on the test bench confirm the high expectations – with a BMEP of 1.8 MPa it was possible to verify NOx values of a non-optimized system of 30 ppm (70 mg/Nm³ @ 5 % O2) with very high combustion stability. In the meantime, GEJ can look back at 6 years of excellent experience and can see itself as the “technological leader” in the field of laser ignition. Despite this, considerable developmental steps are still necessary to...

Advanced Laser Case Study

...Case 2: Advanced Laser Clinics In the case, “Advanced Laser Clinics,” a clinic in Austin Texas is a bottom-performing store that is desperate for some positive changes. Elizabeth Ryan is the new manager who was hired to bring about those changes. There were several issues identified within this case. The first issue that I recognized was the inexperience of Ryan as a manager within this particular field. Her experience was working with the Navy, where she dealt with mainly men. Even though she has years of leadership experience, the beauty industry is completely new to her as well as working with other women. She also only received four days of training, which seems minimal. The other issue presented in the case was between the two technicians. Gulford complained about the body odor of Moore. Gulford stated that it was directly affecting their work environment when the customers could not stand the odor and even had to take breaks during treatments because of it. Gulford also mentioned some issues with the location and marketing of the clinic, but the odor seemed to be the most pressing issue. Ryan needs to address this issue with Moore and prepare for a meeting with her. The most important thing that Ryan needs to focus on is trying her best not to upset Moore. She does not want Moore to have low self-confidence and question her ability to do her job. This is particularly important in the beauty industry where appearance has a big effect on advertising. Since the...

Laser Beam Design Idea

...For our shutter we used a spring back solenoid with an attached shutter to move in front of the laser beam when power was cut, e.g. from a kill switch being pressed or the laser door being opened. We put the solenoid shutter mechanism in a box with a hinged front face and two holes, one in either side so the laser beam can enter and leave the box, when the shutter is in the off position blocking the laser it will be blocking the exit hole this means that if the laser reflects for any reason it will be contained in the sealed box preventing it causing any damage to anyone. Also the hinged front face of the box means that if there is any maintenance to be carried out then the solenoid mechanism can be accessed easily. The casing is made to specifications so that it does not block any airways on the laser or to affect the accuracy of the laser beam. The hole at the back of the box, connecting the laser has a diameter 4mm larger than the front hole, which has the same diameter of the laser emitter; this is so that it can fit over the emitter easily. The hole at the front is made as small as needed so that the shutter can block out the whole hole easier. The box should be machined from a solid piece of aluminium, because it is light soothe bolts could hold it in place, and hollowed out from the front face. The front face should also be made out of aluminium sheet metal. Using a boring drill bit a 64 mm diameter hole should be drilled on the back face and then a 60mm hole should be......

Communication

...Pre-Class Survey What is communication? There are different types of meaning of communication. Communication can be an act of processing and understanding between two or more individuals in settings. Communication can be a way of expressing through signs, exchange of feelings, and behaviors. The purpose of communication? The purpose of communication is to understand each other in a group setting. Also, help individual express the needs and wants of others. What is good communication? Good communication is the skill to an effective communication. Without good communication skills, messages can be receive in error, and misleading to an individual. To understand verbal and nonverbal communications, here are a few examples; Verbal communication is a form of communicating through expression, words, telephone, speeches, and face-to-face communication. Nonverbal communications are no spoken communication that considered as hand gestures, eye contact, appearance, and facial expression. My experience with team or groups communication has been good and bad experience. The good experience I had is when every team member can communicated and collaborate with a project, and have the same goal in mind as other team members. The bad experiences are team members or a group that has major conflicts, and confusion completing task that need to be completed Many team members or individuals do not contribute to their assignment and having team members who are lazy, or......

Medical Laser Equipment

...INTRODUCTION This Paper analyzes the Case 16: Medical Laser Equipment. Some of the given facts are as follows: Order is set to every Monday which means an annual total of 50 orders No. of Periods = 250 Days Annual Demand = 166 Units Average Inventory = 5 Units Order Cost = $95 Stock out Cost = $250 Holding Cost = 50% * $1,000 = $500 Capital Cost = 10% Handling Cost = 15% Obsolescence = 5% Storage Cost = 20% We started the case analysis by the normality test for the current data to check if the data is normally distributed or not. Our objective is to calculate the current Total Cost and then come up with a better solution to lower the cost. As a result, we have developed two scenarios, both of them reveled lower cost than the current one. Below is detailed analysis. NORMALITY TEST Knowing the nature of our data is a key factor for deciding upon the appropriate way to propose a new modeling scenario. As a fact, most of the popular statistical techniques assume that studied data are normally distributed under certain conditions. Therefore, a normality test was performed to: Test if demand is well-modeled by a normal distribution or not. Find out descriptive statistics about the demand distribution such as mean, standard deviation and P-value. Test result revealed that the demand is normally distributed with: Mean = 0.664 Standard Deviation = 0.776 P-Value < 0.005 Below are graphical presentations for test results...

Communication

...Communication Channels Within an Organization By: Jamie Lee What is communication? Communication is the act of exchanging words, thoughts, messages, or information, as by speech, signals, writing, or behavior. It’s the art of using words to impart information or ideas. In any work environment communication is part of your day, how y9ou will complete your assigned duties. Communication is how you will get your point across. In my paper I will explain the different levels of communication and the importance of proper positive communication in your everyday work environment. Intrapersonal Communication is language use or internal thought to the communicator. Intrapersonal communication is the active involvement of the individual in symbolic processing of messages. The indicidual becomes his or her own sender and receiver, providing feedback to him or herself in an ongoing internal process. It can be useful to imagine intrapersonal communication occurring in the mind of the individual in a model which contains a sender, receiver and feedback. Although successful communication is generally defined as being between two or more individuals have argued that this definition is too narrow. Some forms of intrapersonal communication is day-dreaming, speaking aloud, reading aloud, repeating what one hears which increases conmcentration and retention. This is considered normal. Making gestures while thinking and interpreting non-verbal communication. Interpersonal...
