title: Phase-conjugate feedback into a continuous-wave ring dye laser.
abstract: Optical feedback from a BaTiO(3) passive phase-conjugate reflector into an untuned cw ring dye laser can narrow the linewidth to 1.3 GHz. Self-scanning effects are also observed. The linewidth results are interpreted in terms of spatial hole burning and longitudinal-mode competition.
