Relaxation oscillations of the intensity of the radiation from a 2-μm thulium (Cr~(3+), Tm~(3+): YSGG) crystal laser operating under cw and pulsed conditions

摘要

Analytic expressions are derived for and quantitative estimates are obtained of the frequency and damping (decay) decrement of relaxation oscillations of the intensity of radiation from a 2-μm thulium laser with a Cr~(3+), Tm~(3+):YSGG crystal operating under cw and pulsed conditions.
