Periodically modulated emission and the possibility of generating “giant” pulses in a three-level laser using a nonuniformly excited active medium

Summary

The above analysis has shown that nonuniformity of the excitation of the active medium of a laser leads, even in the single-mode approximation, to an increase in the possible motions of the system and, in particular, to the possibility of generating giant pulses and unattenuated periodic self-modulation of emission. Clearly, allowance for a large number of oscillation modes of the optical resonator and a more rigorous calculation of the active medium distribution will considerably widen the class of possible motions and will enable us to explain the complex emission-selfmodulation structure observed experimentally in solid-state lasers.
