Abstract

We present a compact high-efficiency and high-average-power diode-side-pumped Nd:YAG rod laser oscillator operated with a linearly polarized fundamental mode. The oscillator resonator is based on an L-shaped convex-convex cavity with an improved module and a dual-rod configuration for birefringence compensation. Under a pump power of 344 W, a linearly polarized average output power of 101.4 W at 1064 nm is obtained, which corresponds to an optical-to-optical conversion efficiency of 29.4%. The laser is operated at a repetition rate of 400 Hz with a beam quality factor of M(2)=1.14. To the best of our knowledge, this is the highest optical-to-optical efficiency for a side-pumped TEM(00) Nd:YAG rod laser oscillator with a 100-W-level output ever reported.

摘要

我们展示了一种紧凑的、高效且高平均功率的二极管侧面泵浦Nd:YAG棒状激光振荡器，其工作在基模线性偏振状态。该振荡器谐振腔基于一个带有改进模块的L形凸面-凸面腔以及用于双折射补偿的双棒结构。在344W的泵浦功率下，在1064nm处获得了101.4W的线性偏振平均输出功率，对应的光光转换效率为29.4%。该激光器以400Hz的重复频率运行，光束质量因子M(2)=1.14。据我们所知，这是迄今报道的输出功率为100W级的侧面泵浦TEM(00) Nd:YAG棒状激光振荡器中最高的光光效率。
