Generation of efficient subnanosecond self-stimulated Raman pulses by a diode-pumped passively Q-switched Nd:YVO4/Cr4+:YAG laser is demonstrated. Experimental results reveal that self-frequency Raman conversion can be achieved with a c-cut Nd:YVO4 crystal in a nearly hemispherical cavity. At 2.0 W of incident pump power, the self-stimulated Raman laser produces stable 710-ps pulses at a Stokes wavelength of 1178.6 nm with 7.2 microJ of pulse energy at a 17-kHz repetition rate.
演示了通过二极管泵浦被动调Q的Nd:YVO4/Cr4+:YAG激光器产生高效的亚纳秒自激拉曼脉冲。实验结果表明，在近半球形腔中使用c切割的Nd:YVO4晶体可以实现自频拉曼转换。在2.0W的入射泵浦功率下，自激拉曼激光器在1178.6nm的斯托克斯波长处产生稳定的710ps脉冲，脉冲能量为7.2μJ，重复频率为17kHz。
