摘要

以去离子水为冷却剂，钕钇铝石榴石为增益介质，研制了浸没式液冷板状激光器。利用波导实现了高度均匀的泵浦光束分布，并优化了增益模块(GM)通道内的流速分布。在不同流速下，得到了对流换热系数。实验结果表明，该激光器的最大输出功率为434 W，光效率为27.1%，斜率效率为36.6%。据我们所知，这是具有单个Nd:YAG板的浸入式液冷激光振荡器的最高输出功率。

Immersed liquid cooling Nd:YAG slab laser oscillator

An immersed liquid cooling slab laser is demonstrated with deionized water as the coolant and a Nd:YAG slab as the gain medium. Using waveguides, a highly uniform pump beam distribution is achieved, and the flow velocity distribution is also optimized in the channels of the gain module (GM). At various flow velocities, the convective heat transfer coefficient (CHTC) is obtained. Experimentally, a maximum output power of 434 W is obtained with an optical – optical efficiency of 27.1% and a slope efficiency of 36.6%. To the best of our knowledge, it is the highest output power of an immersed liquid cooling laser oscillator with a single Nd:YAG slab.

期刊介绍： Chinese Optics Letters (COL) is an international journal aimed at the rapid dissemination of latest, important discoveries and inventions in all branches of optical science and technology. It is considered to be one of the most important journals in optics in China. It is collected by The Optical Society (OSA) Publishing Digital Library and also indexed by Science Citation Index (SCI), Engineering Index (EI), etc. COL is distinguished by its short review period (~30 days) and publication period (~100 days). With its debut in January 2003, COL is published monthly by Chinese Laser Press, and distributed by OSA outside of Chinese Mainland.
