A novel colliding-enhanced Cr:LiSAF broad-band phase-conjugate resonator (PCR) has been investigated theoretically and experimentally. This kind of PCR is a low initiating threshold resonator. It can produce self-Q-switching narrow pulse with about 35 ns duration (FWHM), efficiently correct intracavity phase aberrations, and severalfold improve output laser beam quality.
