TL;DR: The average output power of pulsed HF chemical lasers was found to depend strongly on the fluorine source used as mentioned in this paper, and the best performance was obtained from H 2 -C 2 F 6 -He mixes, which gave average powers of 850 mW and energies of 20 mJ/pulse.
Abstract: The average output power of pulsed HF chemical lasers is found to depend strongly on the fluorine source used. The best performance was obtained from H 2 -C 2 F 6 -He mixes, which gave average powers of 850 mW and energies of 20 mJ/pulse. Peak gains of at least 0.036 cm-1are observed. Average powers of 450 mW from DF and 70 mW from HCl are reported.

TL;DR: In this paper, two atmospheric pressure CO2 pulsed laser systems were operated with discharges and resonators designed for fundamental mode operation with pulsewidths in the range 40-80 ns and peak powers in excess of 20 MW.
Abstract: Two atmospheric-pressure CO2 pulsed lasers have been operated with discharges and resonators designed for fundamental mode operation. Pulse energies of 50% of the maximum multimode energy have been obtained with pulsewidths in the range 40–80 ns and peak powers in excess of 20 MW. Complete self mode locking has been observed with pulse-widths of less than 3 ns.

TL;DR: In this paper, the authors developed a method which allows comparisons of the wavelengths emitted by two different laser pairs with an accuracy of about 6·10−6, which is the same as ours.

TL;DR: In this paper, an expression for the threshold output power density for spontaneous mode locking in Q-switched laser is derived, and the resulting expression is readily evaluated in terms of laser emission cross section and linewidth and cavity geometry.
Abstract: An expression for the threshold output power density for spontaneous mode locking in Q -switched lasers is derived. The resulting expression is readily evaluated in terms of laser emission cross section and linewidth and cavity geometry. The expression is evaluated for several experiments which previously reported spontaneous mode locking.
