激光器板条激光器端面抽运倒像谐振腔斜率效率 lasers slab laser end-pumped image-inverting resonator slope efficiency

摘要

开展了激光二极管端面抽运Nd:YAG板条激光器的实验研究，根据板条激光介质的特点，通过选择倒像谐振腔，有效地避免了激光光束偏离板条端面和输出功率不稳定的情况。在抽运功率3330 W时，获得了平均功率超过1000 W的准连续激光输出，斜率效率达到42.2%，输出功率的稳定性优于1.5%。实验还测量了激光光束质量并进行了相应的理论分析。

Abstract

The Nd:YAG slab laser with laser diode array end-pumping experiment has been developed. According to the characteristic of slab medium, the slab laser with image-inverting resonator (IIR) avoids effectively the beam excursion to the slab end and the instability on laser power. It obtains the quasi-continuous laser output with the average power higher than 1000 W when the pump power is 3330 W, the slope efficiency is 42.2%, the stability of the output power is better than 1.5%. The beam quality of laser is measured and the relevant academic analysis is done.
