摘要
利用光纤中的各种非线性效应 ,获得了重复频率为 2 .5 GHz、光谱宽度达 60 nm的超连续谱超短光脉冲源。利用两个带宽分别为 0 .4nm及 1 .2 nm的可调谐滤波器 ,从超连续光谱的不同波长处获得了脉宽为 5.7ps及 3.6 ps的超短光脉冲。由实验规律发现 ,在多种非线性效应中 。
The ultrashort pulse source with supercontinuum up to 40~60 nm at a repetition rate of 2.5 GHz was obtained by a variety of nonlinear effects in the optical fiber. The ultrashort pulses with pulsewidth of 5.7 ps and 3.6 ps were filtered from supercontinuum source at different wavelength by applying two optical filters with bandwidth of 0.4 nm and 1.2 nm, respectively. It was demonstrated by experiments that the four wave mixing influenced the generation of supercontinuum greatly.
