Abstract : The present invention is directed toward providing an improved phase-conjugate resonator in which undesirable characteristics are minimized or eliminated. The presented invention employs two moving grating devices as feedback mirrors at both ends of the resonator together with a spatial filter, an output coupler, and a laser gain medium. In particular, at least one of the moving gratings is a Brillouin (SBS) mirror and in some arrangements both gratings may be. It is therefore one object of the present invention to provide for an improved phase-conjugate resonator that eliminates doppler walkoff. Another object of the present invention is to provide for a resonator that can operate in a long-pulse mode without doppler walkoff.
