Development of CARS spectrometer using dual-wavelength electronically tuned laser

The CARS spectroscopy system using the dual-wavelength oscillation electronically wavelength tuned laser as a pumping light source were constructed to realizes more sensitive full range non-chromosomal spectroscopy. Simpler configuration of CARS optical system was realized by using the laser. To realize the CARS system, the methods to synchronize the pulses with two different wavelengths generated from the dual-wavelength oscillation electronically wavelength tuned laser was demonstrated by using sum frequency generation.
