We report on the self-Q-switched laser operation of a monolithic Nd:Cr:YVO(4) channel waveguide cavity. Femtosecond laser inscription was used to fabricate a buried channel waveguide in the substrate. The Nd:Cr:YVO(4) crystal works as both the gain medium and the saturable absorber, which enables the realization of a self-Q-switched waveguide laser pumped at 808 nm and emitting at 1064 nm. The compact waveguide cavity achieved maximum output powers up to 57 mW, corresponding to a single-pulse energy of 22.8 nJ, at 2.3 MHz repetition rate with a pulse duration of 85 ns.
我们报道了一种单片Nd:Cr:YVO₄ 通道波导腔的自调Q激光运转。采用飞秒激光写入技术在衬底中制备了掩埋通道波导。Nd:Cr:YVO₄ 晶体既作为增益介质又作为可饱和吸收体，这使得实现了一种在808 nm泵浦、1064 nm发射的自调Q波导激光器。该紧凑的波导腔在2.3 MHz重复频率、85 ns脉冲持续时间下实现了高达57 mW的最大输出功率，对应单脉冲能量为22.8 nJ。
