    Electrooptic gating and amplification of Pulses with durations from 1 to 5 ns were accomplished with a pulsed HF chemical laser system using SF6-hydrocarbon media and transverse-discharge energization. The system comprised an apertured, pin-discharge multiline oscillator, a MgF2Rochon prism polarizer, a Pockels-effect, fast electrooptic switch, a 5:1 magnifying telescope, and...

    A forced mode locked dye laser system capable of ultra-short pulse formation is examined experimentally, and the magnitudes and relative timing of the dye pulse, the pumping pulse, and the fluorescence are measured. Significant fast inversion loss of the gain medium is noted, and, for normal mode locked operation, only one pulse is observed to circulate in the cavity. A simplified model of the ope...

  • Infrared third-harmonic generation in phase matched CO gas

    Resonance-enhanced third-harmonic generation (THG) of CO2laser radiation has been studied in CO and NO. It is shown that the coherence length for THG in CO can be increased by adding SF6and that phase matching occurs for a CO:SF6ratio of 208:1. The pressure dependence of the third-harmonic conversion efficiency in CO-SF6mixtures has been measured up to 1... View full abstract»

  • Frequency response of CO2laser coupling modulation near intermode spacing frequencies

    The experimental proof for the existence of frequency-response distortions due to cold cavity modes in the output of a coupling-modulated CO2laser is presented. As expected from theory, severe distortions occur if the retardation bias approaches a value where coupling loss and cavity loss are of comparable magnitude. View full abstract»

  • Steady multiply pulsed discharge-heated copper-vapor laser with copper halide lasant

    Discharge-heated radiation-cooled operation of a copper-vapor laser (CVL) using copper chloride and copper iodide as the lasant has been maintained for periods of over an hour. Maximum power was over 4 W and system efficiency over 0.3 percent. Discharge tube temperature of up to 800°C and beam-size reduction to less than half the tube inside diameter (ID) have also been observed. View full abstract»

  • Avalanche initiating electron produced by laser-induced tunneling

    We have been able to eliminate all extrinsic sources of avalanche initiating electrons in ultrapure N2and He gas. Plasma formation is therefore inhibited until the laser intensity glows high enough to produce tunnel ionization of a molecule in the focal volume. This permits a record CO2laser intensity, as high as 1013W/cm2in a high-pressure gaseous targe... View full abstract»
