用钛宝石激光器泵浦单块 (Cr4+ ,Nd3 + ∶YAG)晶体获得了1.0 6 4μm的自调Q激光输出 .激光输出的模式是稳定的单纵模 ,泵浦的阈值功率为 6 3mW ,脉冲宽度 (FWHM)为 8ns,斜率效率高达2 4% .随着泵浦功率的变化 ,脉冲宽度保持不变 ,而重复频率则在变化 .这种把激光增益介质和可饱和吸收体结合到一起的自调Q激光晶体的研究将有利于固体激光器的全固化、集成化和实用化 .
An autotuning Q laser output of 1.06 4μm was obtained by pumping a single (Cr4 +, Nd3 +: YAG) crystal with a Ti: sapphire laser.The mode of laser output was a stable single longitudinal mode with a pumped threshold power of 6 3 mW and a pulse With a FWHM of 8ns and a slope efficiency of up to 24%, the pulse width remains the same as the pump power changes, while the repetition frequency is changing.This combination of laser gain media and saturable absorbers Self-tuning Q laser crystal research will be conducive to the solid-state solid-state laser, integrated and practical.
