摘要
采用光纤耦合激光二极管端面抽运Nd:YVO4激光晶体,抽运光平均功率为20 W,脉冲宽度为100 μs,获得了重复频率为1 kHz、平均功率为1.5 W的再生皮秒脉冲激光输出,脉冲宽度约为15 ps,两个方向上的光束质量因子均小于1.4。
Abstract
A laser diode end-pumped Nd:YVO4 picosecond regenerative amplifier with the repetition rate of 1 kHz is demonstrated. At the pumping power of 20 W and pumping pulse width of 100 μs, a stable output power of 1.5 W is obtained with the extraction efficiency of 7.5%. The pulse width is measured to be about 15 ps, and the beam quality factors M2 in both directions are less than 1.4.
