Abstract
For generation of a light beam having a narrow linewidth, an energy extraction beam of narrow linewidth, typically from a pulsed laser, is directed into a Raman medium having a large stimulated line. A second source, typically a pulsed laser, delivers a beam coaxial to the first in the medium. The frequency of the first beam is within the stimulated emission line of the medium induced by the second frequency and energy transfer occurs from the second to the first beam without substantial increase in the spectral linewidth.
