摘要 利用半导体激光器抽运的Nd:YAG晶体实现了5.4mJ、1kHz的532nm皮秒激光放大器,由自制的皮秒振荡器种子源、一级再生放大器、一个两通放大器、一个主放大器和倍频器组成。得到绿光的光束质量因子在切线和弧矢方向分别为1.39和1.96,功率不稳定度小于0.3%。 We demonstrate a 532 nm and 1 kHz picosecond laser amplifier which is made up of one home-made picosecond oscillator seed, a regenerative amplifier, two-pass amplifier, a main amplifier, and a frequency doubler. The green laser has a beam quality factor of 1. 39 and 1. 96 for tangential direction and sagittal direction, respectively, and the long-term stability root mean square (RMS) is less than 0.3 %.
