摘    要:针对激光放大过程中的增益窄化效应 ,采用了窄带干涉滤光片与石英双折射滤光片两种器件对中心波长10 5 3nm ,谱宽 13nm的超短脉冲进行光谱整形。石英晶片的参数由计算机仿真确定。光谱整形的实验结果与数值模拟的结果吻合较好。整形后的光谱形状变为平顶 ,谱宽增加了 2nm。

关 键 词:激光技术  超短脉冲  光谱整形  干涉滤光片  双折射滤光片

Abstract:To alleviate gain narrowing, the interference filter and the quartz birefringent filter were used to shape the spectrum of ultra-short pulse with the FWHM bandwidth of 13 nm at λ = 1053 nm. The parameters of quartz plate were decided by simulation with computer. The experimental result is coincident with the simulation of the spectrum shaping. The shape of the spectrum becomes flat at its top and the FWHM bandwidth broadens 2 nm.
Keywords:laser technique  femtosecond pulse  spectrum shaping  interference filter  birefringent filter
