实现了一种适合于相干拉曼光谱探测的宽带超连续谱光源的方法，使用1 064 nm飞秒激光泵浦全正色散光子晶体光纤，并用光栅对对脉冲进行压缩，最终获得了脉宽178 fs，频谱范围处于760~1 300 nm的超连续谱光源.对超连续谱脉冲的时间频谱结构进行了分析，未经过压缩的超连续谱的脉冲宽度达到1.43 ps，不同频率的成分之间延迟较大，但基本上呈线性平滑分布，因此可以使用光栅对进行色散补偿；此外，提高泵浦光的功率虽然能够增加光谱展宽，但会引入高阶色散，并不利于色散补偿.最后，使用该超连续谱搭建的三色相干反斯托克斯拉曼散射光谱探测系统，测量了苯甲腈溶液的相干反斯托克斯拉曼散射信号光谱，同时获得了3 200 cm^-1范围内的所有振动模式，验证了该超连续光谱的性能.

A method of generating broadband supercontinuum pulses is proposed, and it is a prefer light source for coherent Raman spectroscopy.A 1 064 nm femtosecond laser was used to pump the normal dispersion photonic crystal fiber, and then a pair of gratings was used to compress the pulse. Then a supercontinuum light source with a pulse width of 178 fs and a spectral range of 760~1 300 nm was obtained.The temporary spectrum structure of the supercontinuum pulse was analyzed. The results demonstrated that its spectrum is basically linearly and smoothly distributed, but the pulse width reaches 1.43 ps, and the time delay between different spectral frequencies is quite large. Therefore, a pair of gratings is used for dispersion compensation. In addition, although increasing the power of pump light can increase the spectral broadening, it will also introduce higher-order dispersion, which will increase complexities to the following dispersion compensation. In the end, to verify the performance of the supercontinuum in Coherent Anti-stokes Raman Scattering (CARS), three-color CARS spectrum detection system was built using the supercontinuum, and the CARS spectrum of the benzonitrile solution was measured, and all vibration modes in the range of 3 200 cm^-1 was obtained simultaneously.
