摘要
ICF驱动器在脉宽为3ns的长脉冲条件下运行时,三倍频晶体中的横向受激拉曼散射效应将比短脉冲条件下的效应更为显著。针对长脉冲运行时,KDP晶体和KD P晶体产生的横向受激拉曼散射光对晶体的危害性作了对比分析,并研究了横向受激拉曼散射效应与增益系数之间的关系,为选择何种晶体作为三倍频晶体提供了理论依据。
When the laser driver for ICF works in the case of 3ns long pulse, the effect of transverse stimulated Raman scattering in tripler is more significant than that in the case of short pulse. This paper studies the damage of transverse stimulated Raman scattering in KD*P is compared with that in KDP and the relation between the effect of transverse stimulated Raman scatterin and gain coefficient. Therefore, it poesents theoretical evidences for choosing which type of crystal as tripler.
