Abstract
A solid-state laser having a smoothly moving lasing material. A closely toleranced, fluid-bearing assembly extends around the slab of moving lasing material for both supporting and cooling the slab of material with a film of a thermally conductive fluid, such as helium. The lasing means, which causes a portion of the lasing material to heat, is immediately adjacent the fluid-bearing assembly, and the heated lasing material is moved into the fluid-bearing assembly for cooling as soon as possible after it has been heated by the lasing operation. The slab of lasing material can be in the form of a rectangular block or a ring with a rectangular cross section. In the first case, the slab of lasing material is moved through the fluid-bearing assembly in a back-and-forth motion by a transport mechanism. In the second case, the ring is cooled by driving it through the fluid-bearing assembly in a single direction.
