Continuous-wave Nd:YLF laser diode-pumped at 908 nm

We report what we believe is the first demonstration of a continuous-wave Nd:YLF laser under in-band diode pumping at 908 nm. The laser produced the maximum average output power of 750 mW at 1047 nm. The maximum slope and optical-to-optical efficiencies were 64.6% and 39.5%, respectively, with respect to the absorbed pump power. The maximum output power was limited by the available absorbed pump power and not the thermal effects. The results that are presented in this work are preliminary and further work is in progress to improve the efficiency of the laser system.

我们报道了我们认为是在908纳米带内二极管泵浦下连续波Nd:YLF激光器的首次演示。该激光器在1047纳米处产生了750毫瓦的最大平均输出功率。相对于吸收的泵浦功率，最大斜率效率和光 - 光效率分别为64.6%和39.5%。最大输出功率受可用的吸收泵浦功率限制，而非热效应。本文所呈现的结果是初步的，目前正在进行进一步的工作以提高激光系统的效率。
