Abstract
A laser profile consisting of 113 coupled Gaussian waves is obtained i n a cw oscillator by use of a BaTiO3 crystal as both an amplifying med ium and a phase-conjugating mirror. Mutual locking of Gaussian waves i s performed by a pair of spatial filters. One of them is a high-resolu tion holographic component; the other is an opaque screen with identic al circular apertures.
