摘要
在这项研究中，我们展示了一种由工作波长为 2.05 μm 的电子光学二极管泵浦 Ho :GdVO4 激光器产生的高峰值功率 Ho :YLF 放大器。二极管泵浦 Ho :GdVO4 激光器在连续波（CW）模式下工作，在吸收泵浦功率为 28 W 的情况下，输出功率达到 7.1 W，斜率效率为 41.4%。在 1 kHz 的重复频率下，该激光器的平均输出功率为 3.6 W，脉冲宽度为 4.3 ns。利用 Ho :YLF 晶体作为放大介质，种子功率为 3 W，入射泵浦功率为 22.5 W，放大器产生的平均输出功率为 15.5 W，脉冲宽度为 4.5 ns。我们计算出最大脉冲能量和峰值功率分别为 15.5 mJ 和 3.4 MW。
High Peak Power Ho : YLF Amplifier at 2.05 μm Seeded by an Electro-Optically Diode-Pumped Ho :GdVO4 Laser
In this study, we present a high peak power Ho :YLF amplifier seeded by an electro-optically diodepumped Ho :GdVO4 laser operating at 2.05 μm. The diode-pumped Ho :GdVO4 laser, operating under a continuous-wave (CW) regime, achieved an output power of 7.1 W at an absorbed pump power of 28 W, resulting in a slope efficiency of 41.4%. At a repetition rate of 1 kHz, the laser delivered an average output power of 3.6 W with a pulse width of 4.3 ns. By utilizing a Ho :YLF crystal as the amplification medium, with a seed power of 3 W and an incident pump power of 22.5 W, the amplifier generates an average output power of 15.5 W with a pulse width of 4.5 ns. We calculate the maximum pulse energy and peak power to be 15.5 mJ and 3.4 MW, respectively.
