利用Nd:GGG晶体开展了非稳腔的设计研究,通过对抽运系统的优化设计,使抽运均匀性提高到94%;建立了热力学计算模型,计算得到了激光介质的温度分布,实验验证了计算模型的可靠性;利用非稳腔理论分析模型优化了非稳腔的设计参数,实现了输出功率大于10 kW、平均光束质量为5.84倍衍射极限的激光输出。
Abstract
The design of unstable resonator has carried out by Nd:GGG. Coupling system is optimistically designed to get the uniform of gain distribution to 94%. Thermal simulation module is established and temperature-distribution of laser medium is calculated. The simulation module is attested by the experimental results. Then the design parameters of unstable resonator are optimized by theoretically analytical module of unstable resonator. The experimental results show that the output power is more than 10 kW and the average beam quality is 5.84 times diffraction limit.
