ABSTRACT:
An infrared laser system includes a neodymium laser for generating a pulsed laser beam at a wavelength of 1.06 micrometers and a Raman cell containing a Raman active medium. The laser beam, having sufficient peak power to cause emission of light from the Raman active medium by stimulated Raman scattering, is directed through the Raman cell. Ethanol-d.sub.1 or methanol-d.sub.1 is used as the Raman active medium to generate wavelengths of about 2.8-2.9 micrometers. The laser is preferably a neodymium YAG laser.
