Abstract: A mounting arrangement for an optical element, such as gain medium, for a laser, optical amplifier or other optical systems is disclosed. The mounting arrangement is applied to a vane assembly for cooling by a gas or liquid stream. The vane assembly comprises: an optical element; a vane plate having an aperture, the optical element mounted in the aperture; and a retainer arranged to fit between the optical element and the vane plate to provide a compressive force at the edge of the optical element to hold the optical element in the aperture. The retainer may be a resilient element or spring element. The retainer may be held in position using retaining rings.

Abstract: A mounting arrangement for an optical element, such as gain medium, for a laser, optical amplifier or other optical systems is disclosed. The mounting arrangement is applied to a vane assembly for cooling by a gas or liquid stream. The vane assembly comprises: an optical element (162); a vane plate (160) having an aperture, the optical element mounted in the aperture; and a retainer (170) arranged to fit between the optical element and the vane plate to provide a compressive force at the edge of the optical element to hold the optical element in the aperture. The retainer may be a resilient element or spring element. The retainer may be held in position using retaining rings. The optical element may be a Nd:YAG laser disc cooled by circulating He gas and the edge of the laser disc may be electrically heated to decrease the temperature gradient within the pumped laser disc. Reduction of thermally induced aberrations within high power lasers.
