Abstract :
A technique for operating a tunable laser simultaneously at two wavelengths has been applied to the infrared HF chemical TEA laser. The two output beams are independently tunable, collinear, and have mutually perpendicular polarizations. Because of collisional coupling between the vibrational-rotational (V-R) levels, the effect of stimulated emission on one set of levels can strongly affect the gain on a different transition.
