摘要
研究了激光二极管(LD)端面抽运的主动调Q内腔式Nd∶YAG/GdVO4拉曼激光器的激光特性, 测量了不同抽运功率和脉冲重复频率条件下的平均输出功率和脉冲宽度。当注入的抽运功率为7.44 W, 脉冲重复频率为20 kHz时获得的1174.5 nm拉曼光的最大平均输出功率为1.3 W, 对应的光-光转换效率为17.4%; 当注入抽运功率为6.8 W, 脉冲重复频率为15 kHz时获得的1174.5 nm拉曼光的最大单脉冲能量为74.4 μJ。与Nd∶GdVO4自拉曼激光器进行实验比较和分析, 实验结果表明主动调Q内腔式Nd∶YAG/GdVO4拉曼激光器可以获得比Nd∶GdVO4自拉曼激光器更高的平均输出功率和转换效率。
Abstract
The characteristics of a laser diode (LD) end-pumped actively Q-switched Nd∶YAG/GdVO4 Raman laser are studied. The average output power and pulse width are measured at the different pump power and pulse repetition frequency. At a repetition rate of 20 kHz and an incident pump power of 7.4 W, an average output power of 1.3 W is obtained, and the corresponding optical-to-optical conversion efficiency is 17.4%. The maximum pulse energy of 74.4 μJ is obtained with a repetition rate of 15 kHz and an incident pump power of 6.8 W. Compared with Nd∶GdVO4 self-Raman laser, the actively Q-switched Nd∶YAG/GdVO4 Raman laser has a higher average output power and a higher conversion efficiency at the same experimental conditions.
