    High repetition rate Q-switched CO2 laser.
    (Australian Atomic Energy Commission, 1982-03) Hamilton, N; Kelly, JW; Struve, H
    A rotating mirror Q-switched CO2 laser was designed and constructed for use as an excitation source in infrared fluorescence studies. Output power of 33 W was reached in the continuous wave (CW) mode. In the pulsed mode peak powers of 3 kW and pulse widths of 200 ns FWHM have been measured. The repetition rate may be varied between 275 and 1000 Hz and single line operation is selectable with a diffraction grating. The design is compact and economical. The laser has shown freedom from electrical noise and average power stability of the order of 1 per cent; it has operated reliably for more than 1000 hours with a minimum of maintenance.

    A thyratron-switched modular CO2 TEA laser for infrared photochemical studies
    (Australian Atomic Energy Commission, 1982-09) Hamilton, N; Kelly, JW; Struve, H
    A thyratron-switched ultraviolet pre-ionised CO2 TEA laser consisting of four modules connected in series has been designed and constructed. The laser can be operated in the TEM 00 mode and is able to produce 2.5 J per pulse. The design and operation of the laser as a tool for infrared studies is discussed together with an evaluation of the effect of operating parameters on output characteristics.
