The book, 'Laser Physics and Technology', addresses fundamentals of laser physics, representative laser systems and techniques, and some important applications of lasers. The present volume is a collection of articles based on some of the lectures delivered at the School on 'Laser Physics and Technology' organized at Raja Ramanna Centre for Advanced Technology during March, 12-30, 2012. The objective of the School was to provide an in-depth knowledge of the important aspects of laser physics and technology to doctoral students and young researchers and motivate them for further work in this area. In keeping with this objective, the fourteen chapters, written by leading Indian experts, based on the lectures delivered by them at the School, provide along with class room type coverage of the fundamentals of the field, a brief review of the current status of the field. The book will be useful for doctoral students and young scientists who are embarking on a research in this area as well as to professionals who would be interested in knowing the current state of the field particularly in Indian context.

Discusses starting from the basics of laser physics and technology to the current status of the field Covers important applications of lasers Provides an overview of the R&D activities being pursued in India on Lasers and their applications

Dr. Gupta is a Fellow of the Indian Academy of Sciences, Bangalore, and National Academy of Sciences, Allahabad. He has received the N.S. Satyamurthy memorial award of Indian Physics Association for the year 1988 for his contributions on mid-infrared coherent sources and the 1998 Homi Bhabha Science and Technology Award of the Department of Atomic Energy, for his contributions in the area of biomedical applications of lasers.

Dr. Rajeev Khare received his M.Sc. degree in Physics from Allahabad University. He joined the Laser Division, Bhabha Atomic Research Centre (BARC) in 1986 after graduating from the BARC Training School and worked in the area of tunable dye lasers. Dr. Khare moved to Raja Ramanna Centre for Advanced Technology (RRCAT), Indore in 1988, where he had set-up a laboratory to design and develop tunable dye lasers pumped by copper vapour lasers. He obtained his Ph.D. degree from Indore University in 2000 for his work on resonator schemes for dye lasers pumped by copper vapour lasers. His research interests are mainly in design and development of tunable dye lasers, copper vapour lasers, copper bromide lasers, nitrogen lasers, excimer lasers and high-resolution spectroscopy. Dr. Khare has over 40 publications in peer-reviewed journals and proceedings of conferences and he holds one patent. Dr. Khare presently Headsthe Dye Laser Development Laboratory at RRCAT, Indore.
