To provide high-energy, high-power beams at short wavelengths for inertial-confinement fusion experiments, we routinely convert the 1.05-microm output of the Nova, Nd:phosphate-glass, laser system to its second- or third-harmonic wavelength. We describe the design and performance of the 3 x 3 arrays of potassium dihydrogen phosphate crystal plates used for type-II-type-II phase-matched harmonic conversion of the Nova 0.74-m diameter beams. We also describe an alternate type-I-type-II phasematching configuration that improves third-harmonic conversion efficiency. These arrays provide conversion of a Nova beam of up to 75% to the second harmonic and of up to 70% to the third harmonic.
为了在惯性约束聚变实验中提供短波长的高能量、高功率光束,我们通常将诺瓦钕:磷酸盐玻璃激光系统输出的1.05微米波长转换为其二次或三次谐波波长。我们描述了用于诺瓦直径0.74米光束的II型-II型相位匹配谐波转换的磷酸二氢钾晶体板3×3阵列的设计和性能。我们还描述了一种改进三次谐波转换效率的交替I型-II型相位匹配配置。这些阵列可将高达75%的诺瓦光束转换为二次谐波,高达70%转换为三次谐波。
