Abstract
An improved laser rod cooling system in which a laser rod (18) is cooled by conducting the heat generated thereby to a flexible, cushioning gel (21) which surrounds and contacts the rod along its length and secures the rod within a fully enclosing support (22). The support is thermally conductive and transparent to the pumping energy from a flashlamp (12). The gel material absorbs differential thermal expansion between the rod and its support to avoid any stresses otherwise exerted on the rod, while the complete surrounding of the rod by the support minimizes thermal gradients within the rod. Thus, a light beam with minimal optical distortion is generated by the laser rod.
