Abstract
Iodine vapor is supplied to an oxygen iodine laser by an improved iodine vaporizer. The vaporizer has a radiation transparent window and iodine crystals are contained in the vaporizer. Broad beam radiation from a variable intensity source is directed through the window into the vaporizer where it is absorbed by the iodine crystals, causing the iodine crystals to sublime. The iodine vapor is transported to the laser by a carrier gas flowed through the vaporizer. Coarse control of the iodine flow is achieved by controlling the carrier gas flow. Control of the amount of iodine vapor introduced into the carrier gas flow is achieved by varying the amount of radiation directed into the vaporizer.
