Phase conjugate fluorozirconate fibre laser operating at 800nm
Optics Letters, 17, (23), . (doi:10.1364/OL.17.001676).
We report phase-conjugate feedback into a fluorozirconate optical fiber amplifier at infrared wavelengths. By using a semiconductor laser diode at 807 nm, a grating is established in photorefractive BaTiO3 that, in the ring configuration, provides feedback into the amplifier necessary for laser action. Once written, the grating is self-sustaining, and lasing is observed even after the laser diode is removed.
