Abstract
Dramatic reduction of the number of oscillating modes in CW and pulsed lasers has been observed using a photorefractive crystal placed inside the cavity. Reflective Bragg gratings recorded by the standing waves inside the crystal act with the output coupler as a self-adapted Fabry-Perot filter. Its spectral characteristics enhance mode competitions which can lead to a single mode operation.
