Simultaneous ultraviolet and infrared emission in a sliding-discharge excited laser

Simultaneous laser action in the UV (337.1 nm and 357.7 nm) and the IR (2.6-3.1 /spl mu/m) spectral ranges is observed in SF/sub 6/-N/sub 2/-propane-butane mixtures directly excited by a sliding discharge. Output energies of 1.1 mJ in the ultraviolet and 12 mJ in the infrared are obtained simultaneously. Some performance parameters of the laser are presented.
