PURPOSE:To generate a laser beam of high output and high quality at a constant divergent angle in a solid state laser for outputting a two-dimensional axial symmetrical laser beam. CONSTITUTION:Two sets of solid state elements 1, 11 are provided in series on an optical path of a laser resonator. One element 1 is excited by a light source 2, a sound wave generating element 9 is mounted on the periphery of the element 11 to drive the element 9, thereby regulating a sound wave output from the element 9 in response to the value of power to the source 2. |
