Pulse shortening in the passive Q-switched all-solid-state two-color lasers with intracavity stimulated Raman scattering

摘要

In this article, the model of Q-switching is presented, which takes into account the stimulated Raman scattering (SRS) within the laser resonator, and report the results of the numerical optimization of the two-color oscillation. We point the main trends of the pulse shortening at fundamental and first Stokes wavelengths, which can be useful for elaboration of the compact sources of the nano- and sub-nanosecond tunable infrared pulses.
