LASER SYSTEMS AND APPLICATIONS provides the foundation for understanding the subject of lasers. The topics included in this book are various experiments that led to the foundation of quantum mechanics, concepts of atomic and molecular spectra. Basic concepts of lasers, solid, liquid and gas lasers, Q-switching and mode locking are described. The applications of laser to material processing, medicine and surgery, holography, optical communication, Lidar, military, meteorology, isotope separation, nuclear fusion are discussed.communication, Lidar, military, meteorology, isotope separation, nuclear fusion are discussed.

• • Emphasis on physical basis of the subject without undue neglect of mathematical aspect • Short questions and answers, solved examples and problems at the end of each chapter • Students appearing for NET , GATE and other competitive examinations will find this book useful
