Infrared laser spectroscopic imaging based on degenerate four-wave-mixing spectroscopy combined with frequency-upconversion detection.
Frequency-upconversion detection of an infrared degenerate four-wave-mixing image was proposed for infrared laser spectroscopic imaging of species in the gas phase. The operation of the imaging system has been demonstrated by observation of an expanding Cs plume generated by laser ablation.
