Abstract
The present invention provides a means to generate a Raman-shifted output from a pump laser source. Multiple embodiments all provide a manner of producing an off-resonant, continuous wave, Raman laser by using a pump laser source having a low power. This is accomplished by using a Raman medium within a cavity having a high finesse.
