title: Controlled scanning of a continuous-wave dye laser with an intracavity photorefractive element.
abstract: An intracavity photorefractive crystal is used in a cw dye laser. The frequency selection of the grating written in the crystal by the laser's standing-wave intensity pattern reduces the laser spectrum to a pair of hole-burning modes. The wavelength can be tuned by varying the laser-cavity length. Wavelength scans across an entire gain curve are possible without mode hops.
