Self-scanning of a dye laser due to feedback from a BaTiO(3) phase-conjugate reflector.
Feedback from a self-pumped BaTiO(3) phase-conjugate reflector into an untuned cw dye laser produces substantial line narrowing (4-6 GHz) and generates a recurrent wavelength sweep from the rhodamine 6G peak at 618 nm to as far as 644 nm.
