Abstract
A laser device has a plasma discharge region for dissociating a diatomic gas into atoms. A nozzle connects the plasma discharge region with an optical cavity. The nozzle expands the plasma accelerating it to a supersonic velocity as it passes from the discharge region into the optical cavity. As the plasma passes through the nozzle, the dissociated atoms are recombined into molecules in a metastable energy state. The nozzle includes a gas injector for introducing a lasing gas into the plasma flow through the nozzle.
