Study on Material Processing of Chemical Oxygen Iodine Laser

This work describes a chemical oxygen iodine laser (COIL) equipment and its application for material processing of cutting and welding. The COIL is capable of delivering high-power output. The shortwavelength (1315 nm) is suitable for the transmission using optical fibers with excellent beam quality. These characteristics make COIL a candidate for a variety of industrial applications in cutting and welding. A cutting application in decommissioning of nuclear reactors is one purpose of high power COIL system and a welding application in heavy industries of thick material is another purpose. The most important key requirement for an industrial laser is low operating cost. At this point of view there are many kinds of problemsto be solved for industrial application of COIL.
