啁啾匹配OPCPA方案用于消除超短激光脉冲的预脉冲
Chirp-matching OPCPA scheme for eliminating pre-pulse of ultrashort laser pulse
摘要
Abstract
The paper proposes a method using chirp-matching optical parametric chirped pulse amplification (OPCPA) scheme to eliminate the pre-pulse within the gain time window defined by the pump duration is proposed. The effects of the pump pulse shape, as well as the delay time between main pulse and pre-pulse on the improvement of signal-to-noise ratio are analyzed, using numerical simulation Comparing the chirp-matching OPCPA scheme with the conventional noncollinear OPCPA scheme, it is shown that the chirp-matching OPCPA scheme can eliminate a pre-pulse which is much closer to the main pulse, and it depends less on the pump pulse shape.关键词
