Abstract : In accordance with the present invention, there is provided a short wavelength chemical laser device which utilizes iodine monofluoride as a lasing medium. The device is an optically pumped iodine monofluoride laser in which the ground state iodine monofluoride is produced by reacting iodine and fluorine to form a flame within which the monofluoride is produced. The monofluoride is then pumped or excited with a high energy, broadband dye laser. The device of this invention has particular utility as a gain probe for chemically generated IF lasers and as a useful prototype to study lasing in reactive flows. It can be used to obtain output spectra and powers, as well as study reactant densities and the effects of mixing on visible lasing. Such data is invaluable in designing and constructing visible lasers. The primary object of this invention is to provide a simple, efficient and dependable short wavelength gas laser. Another object of this invention is to provide an optically pumped gas laser in which the lasing medium is chemically produced in the optical resonator of the laser immediately before lasing commences. Still another object of this invention is to provide a gas laser in which visible lasing occurs within the flame resulting from the chemical reaction utilized to produce the lasing medium.
