    Pulse stretching due to partial temporal overlap of two modes in a TEA CO2 laser (2000)
    [S.l.] : American Institute of Physics (AIP)
    Review of Scientific Instruments 71 (2000), S. 579-580 
    Details
    ISSN: 1089-7623
    Source: AIP Digital Archive
    Topics: Physics , Electrical Engineering, Measurement and Control Technology
    Notes: Pulse duration as long as 14 μs has been obtained from a single longitudinal mode TEA CO2 laser. Such stretching occurred under conditions for which oscillation on a higher order transverse mode followed that on the TEM00 mode with partial temporal overlap between the two. Control of the intracavity aperture size in conjunction with cavity length tuning helped realize such an oscillation condition. © 2000 American Institute of Physics.

    Diode-less operation of a resonantly charged repetitive high voltage pulser circuit (2001)
    [S.l.] : American Institute of Physics (AIP)
    Review of Scientific Instruments 72 (2001), S. 2505-2507 
    Details
    ISSN: 1089-7623

    Topics: Physics , Electrical Engineering, Measurement and Control Technology
    Notes: We report here that the unique geometry of the rotating dielectric spark gap allows the diode-less operation of a command resonant charging pulser network. An average power of about 3.5 kW with a peak value of 75 MW was switched at a repetition rate of 600 Hz into a dummy load resembling a typical TEA CO2 laser. © 2001 American Institute of Physics.

    Versatile cavity for optically pumped molecular lasers (2001)
    [S.l.] : American Institute of Physics (AIP)
    Review of Scientific Instruments 72 (2001), S. 1343-1345 
    Details
    ISSN: 1089-7623

    Topics: Physics , Electrical Engineering, Measurement and Control Technology
    Notes: We describe here an optically pumped molecular laser cavity configuration which allows near total transmission of pump radiation into the cavity maintaining, at the same time, a high Q value at the lasing wavelength. This also has built into it the capability of elimination of unabsorbed pump radiation, isolation of pump cavity, and suppression of self-focusing effect. The efficient performance of this versatile cavity has been demonstrated in the pulsed operation of a NH3 laser pumped by a transversely excited atmospheric CO2 laser. The low lasing threshold observed here suggests that this cavity can also be employed for the continuous operation of such lasers. © 2001 American Institute of Physics.
