Laser-Induced Interference Filters in Photorefractive Materials
View through CrossRef
We investigate the properties of a laser-induced interference filter in photorefractive BaTiO3. The filter has several control parameters for the reflectance and its high wavelength selectivity makes the filter suited as output mirror of a tuneable single mode infrared semiconductor laser. Furthermore, the interference filter represents a unique simple method for probing higher spatial harmonics in the photorefractive grating.
