Abstract
Method and arrangement for adjusting a mirror to a laser resonator such that the light impinging on said mirror is reflected on itself. A laser beam of an auxiliary gas laser circulates between the mirror to be adjusted and the output coupler mirror of the gas laser. A part of the laser beams reflected by the mirror is decoupled and projected as different light dots on a ground glass screen. By micro positioning of the mirror the different light dots are fused together to one light dot so that the light impinging on the mirror is reflected back on itself. The method and the arrangement allow a fast and exact adjustment of the mirror which further can be easily automated.
