摘要:
在二极管(LD)抽运的Nd∶YVO4激光器中,采用Cr4+∶YAG(钇铝石榴石)作为可饱和吸收体,可获得1.06μm的被动调Q脉冲激光输出.当腔长为9 cm,抽运功率为13.4 W时,得到重复频率为38.5 kHz,平均功率为1.35 W的调Q脉冲序列,其单个脉冲能量为35μJ,脉宽为25 ns,峰值功率为1.4 kW.比较不同腔长下平均功率随抽运功率的变化关系,以及不同抽运功率下的脉冲重复频率、脉冲宽度和单脉冲能量; 分析热透镜效应对输出功率的影响,以及受激粒子上转换效应对脉冲能量的影响,结果表明,理论分析和实验结果相一致.
Abstract:
A Cr4+∶YAG saturable absorber was inserted into a diode-end-pumped Nd∶YVO4 laser and passively Q-switched pulses at the wavelength of 1.06 μm was realized.When the pump power was 13.4 W and the cavity length was 9 cm,the pulse trains with average output power of 1.35 W,repetition rate of 38.5 kHz,pulse duration of 25 ns,single pulse energy of 35 μJ and peak power of 1.4 kW were obtained.In experiment,the relation of average output power versus pump power was studied for different cavity length,and the pulse repetition rate,the pulse duration and single pulse energy were also compared for different pump power.In theory,the influence of thermal lens on the output power was investigated,and the influence of energy-transfer upconversion effect on the pulse energy was also analyzed.The theoretical analysis was consistent with the experimental result.
