Laser flash tube
Abstract
Abstract The present concept is directed to an improved laser pumping source, or flash tube, which is normally located adjacent a rod of lasing material within a cavity having a highly reflective inner surface. Since large amounts of heat are generated, the maximum operating temperature of the unit has been limited by the melting point of the materials which seal the various sections making up the enclosure. Disclosed is a sealing technique whereby the maximum operating temperature may be raised as high as 800* C. In addition, the configuration of the cavity is modified so that a larger percentage of the energy emitted by the flash tube reaches the lasing material thus improving the overall efficiency of the assembly.
