Effect of 355 nm and 1064 nm dual-wavelength conditioning on the bulk damage properties of DKDP crystal
-
摘要: 为了研究3ω预处理、3ω和1ω同时辐照预处理情况后DKDP晶体的3ω损伤特性，建立了双波长预处理和损伤测试实验系统，重点研究了双波长同时辐照预处理情况下1ω能量密度对预处理效果的影响，分析了双波长同时辐照预处理过程中的能量耦合机制。研究结果表明：双波长同时辐照预处理在提升DKDP晶体抗3ω激光损伤性能方面的效果明显好于单波长预处理；在双波长同时辐照预处理情况下，远低于自身预处理阈值的1ω参与了预处理作用过程；在相同3ω能量密度、能量阶梯的预处理策略下，1ω能量密度存在最佳值。Abstract: To study the 3ω damage characteristics of DKDP crystals after 3ω conditioning, 3ω and 1ω conditioning at the same time, a dual-wavelength conditioning and damage test experimental system was established. The conditioning effects of 1ω energy density under dual wavelength irradiation were studied emphatically. The energy coupling mechanism in the conditioning process of dual-wavelength irradiation was analyzed. Research results show that the effect of dual-wavelength conditioning is significantly better than that of single wavelength. In the case of dual-wavelength simultaneous irradiation conditioning, the 1ω which is far below the threshold value of its own conditioning participates in the conditioning. Under the same conditioning strategy of 3ω energy density and energy gradient, there is an optimal value of 1ω energy density.
