Abstract
An experimental investigation was made of the passive mode-locking of a uv-preionized CO2 laser operating in an unstable wavelength-selective resonator using SF6,BCl3 and N2F4 as bleachable gases. Stable repetitive pulse trains with individual pulses having energies as high as 2J and 2 ns duration have been obtained on a large number of P and R transitions of the 00 degree 1 - 10 degree 0 at 10.6 mu m. Use of the selectively absorbing gas C2H5OH in the resonator has enabled the production of clean, mode-locked pulses by the saturation of N2F4 without the need of an optical dispersive element.
