摘要
根据激光核聚变 ( ICF)物理实验中整形脉冲对倍频器的要求 ,对高功率密度下的 KDP晶体 / 角度失谐和 / 偏振失配双倍频双混频两种高效三倍频方案进行了详细的模拟计算和对比分析 .结果表明 :该方案具有动态范围大、调节精度降低等优点 。
Based On big dynamic and high power Nd∶glass laser radiation,the tripling characteristics of two types of third harmonic generation schemes is investegated:type Ⅰ/type Ⅱ angle deturning and type Ⅱ/type Ⅱ polarization mismatch (two doubles and two triples),which have high tripling efficiency for the complex shapes used to drive ignition targets.The results show that these third harmonic generation schemes have bigger dynamic range,lower adjusting precision and have reference value for engineering design.
