BRIEF COMMUNICATIONS: Electrogasdynamic CO2 laser emitting mode pairs and excited by transverse dc or hf glow discharges
A quasi-cw electrogasdynamic CO2 laser was constructed for the first time. It was pumped by a transverse dc or hf glow discharge and emitted mode pairs. The gas was cooled in a planar supersonic nozzle. This arrangement increased the output power (~0.1W) and extended the spectral range of the radiation (16.3-17.2 μ) compared with earlier experiments carried out using a longitudinal discharge in capillary tubes.
