摘要 采用输出波长为1.4 μm的光参量放大器(OPA)作为泵浦源,泵浦0.2m长的光子晶体光纤,观察到光谱展宽现象.实验得到的光谱宽度达58.4nm(1.3708~1.4292μm ),比OPA输出的光谱宽度(30.4nm)展宽28nm. Spectrum broadening was obtained in 0. 2m photonic crystal filber by using the pumping light with wavelength 1. 4 μm and repeat frequencg 250 kHz, 250 fs optical pulses, which was produced by optical parametei amplifier ( OPA). In our experiments the spectral width oi 58. 4 nm ( 1. 370 8 - 1. 429 2 μm) was obtained at 1.4 μm region. The spectrum was broadened over 28 nm than that of the OPA output spectrum.
