Laser tube holder in a laser oscillator

摘要

A laser tube holder allows axial alignment of the laser tube with a laser oscillator. An inner eccentric holder and an outer eccentric holder have eccentric outer surfaces and rotatably support a cylindrical laser tube joint holder on a support plate in the laser oscillator. When the eccentric holders are rotated the laser tube is axially displaced for alignment. Flanges on each of the eccentric holders are disposed on opposite sides of the support plate. An O-ring and a pressure ring disposed in a groove in one of the flanges allow adjustment of the pressure on which the eccentric holder are retained on the support plate.
