ABSTRACT:
A gas laser havinng a cylindrically-shaped discharge tube in which at least one end is terminated with a metal end cap which supports a mirror body in its central area, supports a metal pump stem in a position eccentric to the longitudinal axis of the tube and supports a thermal compensation element in a position opposite and radially symmetrical to the pump stem whereby at gas laser operating temperatures, the compensation element deforms the metal end cap to substantially the same extent as the pump stem so that the influence of cap deformation on the mirror orientation relative to the longitudinal axis of the tube is minimized or at least approximately compensated.
