High-pressure NH3–N2 laser

A pulsed high-pressure (up to 3 atm) NH₃–N₂ laser is described, having an output power of 10 kW at a frequency of 868 cm^–1 and optically pumped by radiation from a TEA CO₂ laser. It was established that when the parameters of the NH₃–N₂ laser resonator and the pump intensity were fixed one could achieve an increase in the operating pressure of the active medium on using a depleted NH₃–N₂ mixture having an increased partial pressure of ammonia.
