Abstract
A continuous wave deuterium fluoride (DF) chemical laser was designed and manufactured, and we have achieved DF laser beam generation with the maximum output power of 101 W. The gain medium is vibration-rotationally excited DF molecules produced by F+D$_2$ cold reaction through supersonic diffusion mixing in an optical cavity. F atoms are produced in a combustor by F$_2$+ H$_2$ reaction and injected into the cavity through a supersonic nozzle. The optimal chemical efficiency was measured to be 5.12% and specific power to be 96.5 J/g.
