Abstract
We have developed two-types of ultrabroadband multiplex coherent anti-Stokes Raman scattering
(CARS) microspectroscopic systems using supercontinuum (SC) light sources. The first system employs
an InGaAs image-intensified CCD camera, which enables us to perform single-shot CARS measurement.
On the other hand, the second system employs a new laser source based on the master oscillator fiber
amplifier (MOFA) configuration, which generates sub-100-ps (85 ps) laser pulses with sub-MHz (0.82
MHz) repetition rate. Owing to the high peak power and high repetition rate, the exposure time for
CARS imaging of polymer beads was significantly shortened to be less than 1 ms (0.8 ms), which was
mainly limited by the readout time of the CCD camera. Using the second system, CARS spectroscopic
imaging was performed for living cells.
