We report on the successful demonstration of second and third harmonic conversion of a high pulse energy, high average power 1030 nm diode pumped Yb-doped yttrium aluminum garnet (Yb:YAG) nanosecond pulsed laser in a large aperture lithium triborate (LBO) crystal. We demonstrated generation of 59.7 J at 10 Hz (597 W) at 515 nm (second harmonic) and of 65.0 J at 1 Hz (65 W) at 343 nm (third harmonic), with efficiencies of 66% and 68%, respectively. These results, to the best of our knowledge, represent the highest energy and power reported for frequency conversion to green and UV-A wavelengths.
我们报告了在大口径三硼酸锂(LBO)晶体中,高脉冲能量、高平均功率的1030纳米二极管泵浦掺镱钇铝石榴石(Yb:YAG)纳秒脉冲激光器成功实现二次和三次谐波转换的演示。我们展示了在515纳米(二次谐波)处10赫兹(597瓦)时产生59.7焦的能量,以及在343纳米(三次谐波)处1赫兹(65瓦)时产生65.0焦的能量,效率分别为66%和68%。据我们所知,这些结果代表了向绿色和UV-A波长频率转换所报道的最高能量和功率。
