Laser theory and Doppler effects
Abstract
Certain aspects related to work on laser theory in the 1960s are discussed, taking into account a realistic model for a gas laser considering single and multimode oscillation. One of the unexpected outcomes was the prediction that the intensity of single-mode oscillation could have a minimum when the Fabry-Perot resonator was exactly tuned to the atomic resonance frequency. The considered work on laser theory required some knowledge and experience of quantum mechanics, electromagnetic theory, optics, atomic physics, and physics of nonlinear systems. An interest in the Doppler effect was also found to be important. Attention is given to the development of K-band magnetron oscillators, work on the fine structure of hydrogen, the theory of the ammonia beam laser, the theory of an optical maser, aspects of Doppler free spectroscopy, and stimulated and spontaneous emission.
