Continuous wave optically pumped Ar lasers were demonstrated using discharges driven by strip resonator micro-arrays or bare metal electrodes powered by short duration, high voltage pulse trains. The micro-array laser exhibited an optical-to optical power conversion efficiency of 55 percent at a total output power of 40 mW. The larger volume pulsed discharge system produced 4.1 W of output power with an optical conversion efficiency of 31 percent. These results were used to validate computational models that predict scaling into the kW range and beyond is feasible for the ArHe lasing medium. Pulsed laser demonstrations have been performed with KrHe and XeHe gas mixtures. Both show promise for scaling.
