    Measurements of the gain of the P(20), 10.6 μ, transition of CO2have been made in a flowing He, N2, CO2amplifier. Both small-signal and saturated gain conditions were investigated as a function of radial position. At low discharge currents, the radial small-signal gain profile followed a J0Bessel function distribution as predicted from the electron ... View full abstract»

    An electrically excited CO2-N2laser has been developed using high repetition rate discharge pulses from a pin electrode array transverse to a supersonic flow. To date volumetric laser power density of 34 W/cm3from a Mach 3 flow at 17-kHz repetition rate and 160-torr static pressure has been achieved. Power densities of at least 150 W/cm3at atmospheric pr... View full abstract»

    The refractive indices of ZnSiAs2, CdGeP2, and CdGeAs2have been determined over a wide range of wavelengths and the optical nonlinear coefficient for second-harmonic generation from the 10.6-μ CO2laser have been measured. The absorption coefficient versus wavelength is given for the above materials as well as for ZnGeP2, a previously disc... View full abstract»

    A repetitively Q -switched Nd:YAG laser was used to produce "eye-safe" radiation near 1.55 μm by stimulated Raman scattering in acetonitrile and in methane with photon conversion efficiencies of 14 percent and 22 percent, respectively. The laser and Stokes beams were mixed in lithium niobate to obtain 6-kW peak power pulses at the difference frequency near ... View full abstract»

    The details of the hole-burning process are studied experimentally and theoretically in a Doppler-broadened gain or absorption line in pure CO2and in CO2-N2mixtures contained in a test cell. The change of absorption or gain of the test cell when irradiated by a saturating laser in a ... View full abstract»
