The invention relates to a laser light beam delivery system for delivering a laser light beam from a source remote from the laser originating the light. The delivery system consists of an optical fiber having a double taper, i.e., a taper portion at each end with the fiber tapering at the input end and at the output end to a diameter substantially greater than the actual diameter of the fiber. This permits high power transmission capabilities in as much as the greater diameter portions distribute the average energy such that no damage to the fiber is presented.

Fiber optic laser beam delivery system

Improvement in a laser having a solid transparent housing with two cavities for respectively holding a laser rod and a pump lamp. The rod is embedded along its total length within the housing; the pump lamp is embedded along its total arc and over a substantial length of each of its electrode regions within the housing. clearance between lamp envelope and housing is held to close tolerances. Optional beam tubes provided at the end of the rod at the housing shield the laser beam from thermal distortion. Flashlamps having a cerium-doped quartz envelope are particularly desirable for pumping this laser.
