Abstract:
A laser profile consisting of 113 coupled Gaussian waves is obtained in a cw oscillator by use of a BaTiO(3) crystal as both an amplifying medium and a phase-conjugating mirror. Mutual locking of Gaussian waves is performed by a pair of spatial f ilters. One of them is a high-resolution holographic component; the other is an opaque screen with identical circular apertures.
