In order to compensate for the gain narrowing and gain saturation effects,and also to improve the signal to noise ratio of the output high-power laser pulse,lots of attention have been paid to the spatial distribution,the temporal profile,as well as the spectrum reshaping in the design of kilo-joule peta-watt chirped pulse amplification(CPA) systems.
在千焦拍瓦高功率啁啾脉冲放大系统设计中,为了尽量消除增益窄化和增益饱和效应的影响,同时尽可能提高高功率激光输出脉冲信噪比参数,激光脉冲时空和光谱的整形问题备受关注。
