Discovered laser action in carbon dioxide (1963) invented the nitrogen carbon dioxide (CO2) laser --- the first gas laser to produce high power radiation continuously (1964). Among military applications, its most striking contribution has been to the "Star Wars" system once promoted by Ronald Reagan and still being.
In this chapter, we will discuss principal applications of lasers in modern medicine. Due to the present boom in developing new laser techniques and due to the limitations given by the dimensions of this book, not all disciplines and procedures can be taken into account. The main intention is thus to focus on the most

APPLICATION OF LASERS IN COMMUNICATION by P. PARIKH, I nbelec Division of Philips India Ltd., Bombay. The report discusses the various factors involved in the laser communication systems. The state of art as regards the different aspects of the modulation, demodulation and the propagation of laser beam for
Many scientific, military, medical and commercial laser applications have been developed since the invention of the laser in 1958. The coherency, high monochromaticity, and ability to reach extremely high powers are all properties which allow for these specialized applications.
201. 8. Laser Applications. Helena Jelinkova, ZdenCk Kluiber. Introduction. Laser radiation in various applications was made use of immediately after the first laser became operational. The ruby laser was designed and constructed by Teodor Maiman in 1960, and as early as 1961 its radiation was used to treat eye and skin
?The Laser is absorbed in a skin layer of workpiece surface by the free electrons within 1 fs . ? Electrons start to convert laser energy into heat energy after 1 ps which is the relaxation time for electron and phonon. ?Heat energy diffuses from skin layer to the bulk material by conduction. Laser energy diffuses (heats) up to
Applications. Unique properties have made the laser an important scientific tool in applications ranging from studies of plasma light scattering and of nonlinear phenomena to the development of instruments for photography and interferometry. by Theodore H. Maiman. WHEN THE LASER was developed in mid-1960, it was
Soon after the first working laser was developed in 1960, researchers began studying the medical uses of lasers. Lasers were first used medically in. 1961 to treat a type of skin discoloration and to repair detached retinas. Presently, lasers are used more and more widely. This article is intended to enumerate only a fraction
Laser and its Applications. 1. Introduction. No other scientific discovery of the 20th century has been demonstrated with so many exciting applications as laser acronym for (Light Amplification by Stimulated Emission of Radiation). The basic concepts of laser were first given by an American scientist,. Charles Hard Townes
