摘要：

We describe and discuss an experiment on the formation of stationary transverse patterns of the optical field in a laser. The gain medium of an optically pumped, traveling-wave laser is in resonance with degenerate Gauss-Laguerre TEM10 and TEM02 transverse modes of the laser resonator. For low pump powers close to the laser threshold, the laser oscillates in the cylindrically symmetric TEM10 mode. A field pattern of broken cylindrical symmetry emerges continuously above a critical pump power level. The experimental observations confirm the theoretical prediction of Lugiato et al. on the spontaneous breaking of the cylindrical symmetry in lasers [L.A. Lugiato, F. Prati, L.M. Narducci and G.-L. Oppo, Optics Comm. 69 (1989) 387]. © 1990.
