我们已经开发了超宽带（>2000 cm（-1））多路相干反斯托克斯拉曼散射（汽车）光谱使用亚纳秒（sub-ns）微芯片激光源。一种专门设计用于产生亚ns超连续谱（SC）的光子晶体光纤已被用于获得超宽带斯托克斯辐射，这使我们能够实现在800至3000 cm（-1）范围内的同时振动激发。我们成功地获得了几种分子液体的多重汽车谱。由于采用亚ns SC的汽车系统结构简单、紧凑，因此可以很容易地应用于超宽带多路汽车显微光谱。
We have developed ultrabroadband (>2000 cm(-1)) multiplex coherent anti-Stokes Raman scattering (CARS) spectroscopy using a subnanosecond (sub-ns) microchip laser source. A photonic crystal fiber specifically designed for sub-ns supercontinuum (SC) generation has been used for obtaining ultrabroadband Stokes radiation, which enables us to achieve simultaneous vibrational excitation in the range from 800 to 3000 cm(-1). We have successfully obtained multiplex CARS spectra for several molecular liquids. Since the CARS system using the sub-ns SC is simple and compact, it can be easily applied to ultrabroadband multiplex CARS microspectroscopy.
