摘要：

Subnanosecond supercontinuum (SC) has been generated by a 1064 nm microchip laser combined with a photonic crystal fiber. The ultrabroadband (>2000 cm(-1)) SC has facilitated multiplex coherent anti-Stokes Raman scattering (CARS) microspectroscopy in the spectral range from 1000 to 3000 cm-1 with lateral and depth spatial resolution of 0.9 and 4.6 mu m, respectively. A clear CARS image of a Nicotiana tabacum, L. cv. Bright Yellow 2 cell has been obtained with high vibrational contrast. (C) 2008 Optical Society of America.
