We report the generation of picosecond pulsed light at a 266 nm wavelength with an average power of 53 W. We developed a picosecond pulsed 1064 nm laser source with an average power of 261 W, a repetition rate of 1 MHz, and a pulse duration of 14 ps, using a gain-switched DFB laser diode as a seed laser and a 914 nm laser-diode-pumped Nd-doped YVO power amplifier. We achieved stable generation of 266 nm light with an average power of 53 W from frequency quadrupling using an LBO and a CLBO crystals. The amplified power of 261 W and the 266 nm average power of 53 W from the 914 nm pumped Nd:YVO amplifier are the highest ever reported, to the best of our knowledge.
我们报告了平均功率为 53 W 的 266nm 波长皮秒脉冲光的产生。我们使用增益开关 DFB 激光二极管作为种子激光和 914nm 激光二极管泵浦 Nd 掺杂 YVO 功率放大器，开发了平均功率为 261 W、重复率为 1MHz、脉冲持续时间为 14ps 的皮秒脉冲 1064nm 激光源。我们通过使用 LBO 和 CLBO 晶体进行四倍频，实现了平均功率为 53W 的稳定 266nm 光的产生。据我们所知，914nm 泵浦 Nd：YVO 放大器的放大功率为 261W，266nm 的平均功率为 53W，这是迄今为止报道的最高值。
