摘　　要：实验研究了具有单斜独居石结构的钒酸镧(m-LaVO_4)晶体的室温拉曼光谱,报道了基于m-LaVO_4晶体作为拉曼增益介质的主动调Q内腔式脉冲拉曼激光器。受激拉曼变频实验以波长为808nm的光纤耦合半导体激光器(LD)作为抽运激发光源,Nd…YAG晶体为产生基频激光的增益介质,融石英声光调Q器为主动调Q元件,采用紧凑的法布里-珀罗两镜平凹谐振腔可有效地产生波长为1170.9nm的一阶斯托克斯脉冲激光。当注入抽运功率为6.51W,脉冲重复频率为30kHz时,实验产生的一阶斯托克斯脉冲激光的最高平均功率为767mW,相应的脉冲宽度为13.8ns,单脉冲能量为25.6μJ,峰值功率为1.85kW。We investigate the room-temperature Raman spectrum of monoclinic monazite-type LaVO4（m-LaVO4）crystal and report a diode end-pumped intracavity actively Q-switched m-LaVO4 Raman laser.In this experiment,a fiber-coupled diode laser（LD）with a wavelength of 808 nm is used as a pumping excitation source,a Nd…YAG crystal is used as a gain medium for generating a fundamental-frequency laser,and a quartz-acoustic-acoustic Qswitch is used as an active Q-switched component.A compact Fabry-Perot cavity composed by two Fabry-Perot mirrors produces a first-order Stokes pulsed laser with a wavelength of 1170.9 nm.When the input pump power is6.51 Wand the pulse repetition frequency is 30 kHz,the experiment produces the first-order Stokes laser with a maximum average power of 767 mW,the corresponding pulse width of 13.8 ns,the single pulse energy of 25.6μJ and the peak power of 1.85 kW.
