ABSTRACT:
A gaseous Raman conversion medium is placed inside a laser resonant cavity to generate tunable laser radiation in the visible, near infrared and far infrared spectral ranges with an improved conversion efficiency and a higher power output. The combination of the laser medium, a gaseous Raman medium and nonlinear sum and difference generation using intracavity conversion produces coherent radiation at a frequency distinct from the frequency emitted by the laser medium. This new frequency is coupled out of the cavity as the desired output.
