Abstract

A direct focussed gas laser is disclosed wherein the last surface 40, 48A, 48B of the output mirror, in the case of a laser where the mirrors are integral to the ends of the laser tube envelope, is shaped such that it produces a cone 42, or wedge shaped 70, beam. A spherical surface provides a cone shaped beam, while cylindrical surfaces produce a wedge shaped beam. In the case of a Brewster type laser, the envelope enclosing windows are correspondingly shaped.
