Passive mode-locking of a large volume tea-CO 2 laser using an unstable resonator configuration
Abstract
An experimental investigation was made of the passive mode-locking of a uv-preionized CO 2 laser operating in an unstable wavelength-selective resonator using SF 6, BCl 3 and N 2F 4 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° 1-10°0 band at 10.6 μm. Use of the selectively absorbing gas C 2H 5OH in the resonator has enabled the production of clean, mode-locked pulses by the saturation of N 2F 4 without the need of an optical dispersive element.
