摘要
开展了高功率板条增益模块在谐振腔内透射波前特性的实验研究,通过改变谐振腔参数完成了不同提取状态下板条增益模块透射波前的测量。实验表明,功率提取状态对板条的透射波前有着明显的影响。在抽运功率为10.8kW时,相对于平凹腔和非对称输出的平平腔,采用双端对称输出的平平腔提取时,板条增益模块的透射波前畸变最小,其波前畸变峰-谷(PV)值小于1.5μm。
Experimental research about the transmission wave-front characteristic of high power slab gain module in resonator is carried out. The measurement of transmission wave-front of slab gain module under different power extraction status is finished through changing the parameters of the resonator. The experiments indicate that the power extraction status influences the transmission wave-front of slab evidently. Compared with the piano-concave resonator and the asymmetric output piano-piano resonator, the transmission wave-front distortion of the slab gain module is the minimal with the symmetrical output piano-piano resonator, the peak-to-valley （PV） value of the wave- front distortion is less than 1.5 μm when the pumping power is 10.8 kW.
