In this work, a Tungsten disulfide (WS) reflective saturable absorber (SA) fabricated using the Langmuir-Blodgett technique was used in a solid state Nd:YVO laser operating at 1.34 µm. A Q-switched laser was constructed. The shortest pulse width was 409 ns with the repetition rate of 159 kHz, and the maximum output power was 338 mW. To the best of our knowledge, it is the first time that short laser pulses have been generated in a solid state laser at 1.34 µm using a reflective WS SA fabricated by the Langmuir-Blodgett method.
在这项工作中，使用朗缪尔-布洛杰特技术制造的二硫化钨（WS）反射型可饱和吸收体（SA）被应用于工作波长为1.34 µm的固态Nd:YVO激光器中。构建了一台调Q激光器。最短脉冲宽度为409 ns，重复频率为159 kHz，最大输出功率为338 mW。据我们所知，这是首次使用通过朗缪尔-布洛杰特方法制造的反射型WS SA在1.34 µm的固态激光器中产生短激光脉冲。
