ABSTRACT:
Method and apparatus for Raman laser oscillation using stimulating Brillouin scattering as well as stimulated Raman scattering. The method comprises generation of a seed beam and condensing of the seed beam to a gas cell using the condensing lens such that part of the condensed beam is scattered by stimulated Raman scattering while the other part of the condensed beam is scattered by stimulated Brillouin scattering. The stimulated Raman scattered laser beam is outputted from a collimating lens while the stimulated Brillouin scattered laser beam returns to the condensing lens thanking for its phase conjugate characteristic. The stimulated Brillouin scattered laser beam is amplified in a section between a phase conjugate mirror and the resonance reflection mirror and condensed to the gas cell such that it is again scattered by stimulated Raman scattering in the gas cell prior to its output from the collimating lens. The phase conjugate mirror coincides with a focus of the condensing lens, and the section between the phase conjugate mirror and the resonance reflection mirror defines a Brillouin resonator.
