ABSTRACT:
A laser arrangement includes an outer envelope and an inner alumina tube between which insulating material is located. The insulating material has a plurality of apertures therein in its transverse end faces, the aperture being arranged at each end on two circle of similar radii. Hydrogen reservoirs are located within the apertures. During operation of the laser arrangement, the reservoirs become heated causing hydrogen to be evolved and diffused through to the laser active medium, improving the efficiency of the laser operation. When laser action ceases, the arrangement cools and hydrogen returns to the reservoirs. Efficiency enhancing gases other than hydrogen may be used in the arrangement.
