摘要

研究了激光束的 Nd:YAG 多级光放大器的特性，该放大器的空间参数通过在每级放大器有源元件中形成的热透镜进行校正。放大器的有源元件采用激光二极管横向泵浦的 Nd:YAG 晶体。结果表明，移除透镜补偿器可减少放大器的总光学损耗，并提高其紧凑性。具有五个放大级的光放大器的光学损耗为 16%，通过有源元件的热诱导透镜对放大光束特性进行校正；其线性尺寸比放大级之间具有四个双透镜补偿器的五级放大系统的类似指标小 13%。

Multistage Diode-Pumped Nd:YAG Optical Amplifier with Correction of Amplified Laser Beam by Thermally Induced Lenses of Active Elements

The characteristics of an Nd:YAG multistage optical amplifier of a laser beam, the spatial parameters of which were corrected by thermal lenses formed in the active elements of each amplifier stage, were studied. Nd:YAG crystals transverse-pumped by laser diode units were used as the amplifier active elements. Removal of lens-compensators was shown to reduce the total optical losses of the amplifier and enhance its compactness. The optical losses of an optical amplifier with five amplification stages and correction of the amplified beam characteristics by thermally induced lenses of active elements were 16%; its linear dimensions, 13% less than similar indicators for a five-stage amplification system with four two-lens compensators between amplification stages.
