Abstract

Laser action on neutral Xe transitions has been achieved at 1-atm pressure in Ar-Xe and He-Xe mixtures excited in an ionizer-sustainer mode of discharge. A number of near-infrared lines oscillated in both mixtures with the strongest at 1.73 μm in Ar-Xe. Over-all conversion efficiencies of 0.2% in He-Xe and 1% in Ar-Xe were obtained with resulting output powers of 100–200 kW. These represent an order-of-magnitude increase in power, energy per pulse, and efficiency over previously reported observations on conventional transverse discharge lasers.
