| 摘 要： | 采用激光二极管（LD）抽运、主动调Q的方式，利用c向切割的Nd：GdVO4晶体的自受激拉曼散射（self-SRS）效应，实现了结构紧凑、高效的脉冲拉曼激光器。在输入功率为1．8W，主动调Q10kHz时，自受激拉曼激光器产生了稳定的1176nm的斯托克斯（Stokes）脉冲光，斯托克斯光的单脉冲能量为10μJ，脉冲宽度为19ns。此时，自受激拉曼散射的阈值仅为510mW，斯托克斯光的转换效率为5．6％。实验结果表明，有效的自受激拉曼变频可以通过一个c向切割的Nd：GdVO4晶体，采用主动调Q的方式来实现。

| Abstract: | Generation of compact and efficient self-stimulated Raman pulses by a laser diode (LD) pumped actively Q-switched c-cut Nd:GdVO4 laser is demonstrated. At 1.8 W incident pump power, the self-stimulated Raman laser produces stable 19 ns pulses at a Stokes wavelength of 1176 nm with 10 μJ pulse energy at 10 kHz repetition rate. The threshold of the self-stimulated Raman laser is 510 mW, the conversion efficiency from the diode pump to the Stokes is 5.6%. Experimental results reveal that efficient self-stimulated Raman conversion frequency can be achieved with a c-cut Nd:GdVO4 crystal and actively Q-switched. |
