【摘要】：采用相位調(diào)制技術產(chǎn)生的具有一定光譜分布的相位調(diào)制脈沖可以有效抑制高功率激光驅動器中大口徑光學元件的橫向受激布里淵散射和滿足光束勻滑需求,但該脈沖在裝置各系統(tǒng)傳輸放大過程中,由于光譜畸變會引起幅頻調(diào)制(FM-to-AM)效應,這種效應嚴重影響了激光裝置的輸出性能及實驗效果。介紹了相位調(diào)制脈沖產(chǎn)生原理、引起FM-to-AM效應的根本原因及因素,綜述了目前美國的國家點火裝置、法國的兆焦耳裝置以及我國的神光-Ⅲ主機裝置在FM-to-AM效應抑制技術方面取得的重要進展。
[Abstract]:The phase modulation pulse with certain spectral distribution produced by phase modulation technique can effectively suppress the transverse stimulated Brillouin scattering of large aperture optical elements in high power laser driver and meet the demand of beam smoothing. However, during the transmission and amplification of the pulse in each system of the device, the amplitude-frequency modulation (AM-to-AM) effect is caused by the spectral distortion, which seriously affects the output performance and experimental results of the laser device. This paper introduces the principle of phase modulation pulse generation, the fundamental causes and factors of FM-to-AM effect, and summarizes the current national ignition devices in the United States. The MJ device in France and the Shenguang-鈪，
