我们提出了一种紧凑的实验方案，用于在室温下基于 Pr: YLF 晶体的 604 nm 低重复率、高能量纳秒激光器。对 Pr: YLF 晶体的热效应进行了模拟，结果表明，通过适当的晶体和激光输出耦合等参数，可以在室温下产生高能 604 nm 激光线。然后通过实验开发了由脉冲 444 nm 光学参量振荡器泵浦的稳定 604 nm 橙色激光器。获得了 63 μJ 的高脉冲能量，脉冲持续时间为 30 ns，重复率为 10 Hz。据我们所知，这是在室温下使用增益开关泵浦源的此类高能 604 nm 激光器的第一份报告。
We proposed a compact experimental scheme for a low repetition rate, high-energy, nanosecond laser at 604 nm based on Pr: YLF crystal at room temperature. The thermal effect of Pr: YLF crystal was simulated, which demonstrated that high energy 604 nm laser line at room temperature can be generated with appropriate parameters such as crystal and the laser output coupling. Then a stable 604 nm orange laser pumped by a pulsed 444 nm optical parametric oscillator was developed experimentally. A high pulse energy of 63 μJ with 30 ns pulse duration at a repetition rate of 10 Hz was obtained. To the best of our knowledge, this is the first report of such a high-energy 604 nm laser using a gain switched pump source at room temperature.
