目前,惯性约束聚变激光驱动器前级的发展方向是以稳定性好的激光二极管取代原来的闪光灯泵浦,以集成光学和光纤技术取代原来的块状光学调制器进行激光脉冲的整形工作。本文从实验上研究了以激光二极管泵浦的固体激光器作为光源,以波导调制器作为整形器件的激光脉冲的整形和频谱展宽技术,获得了初步的实验结果。

Up to now, the development of the first stage of ICF solid state laser driver is to replace the pumping flash lamp by the laser diode which has much better stability and to replace the buik optic modulator by integrated optics and fiber techology for laser pulse forming. We study experimentally the laser pulse forming techology using a laser diode pumped solid state laser and a integrated waveguide modulator. The foundmental results are obtained which will be of great importance to the laser pulse formation of the new ICF laser drive system.
