Unidirectional Doppler-free gain and generation in optically pumped lasers
Abstract
It is possible to completely compensate for Doppler broadening of the gain line of an amplified wave propagating in a certain direction and a laser theory based on this effect is presented. The gain conditions are analyzed at Doppler-free transitions, the Doppler broadening being compensated by pump-induced light shifts. The spectral characteristics and generation features at the given transitions are studied. The advantages of using a Doppler compensating pump and the feasibility of observing a unidirectional emission in ring cavities is considered.
