  • RF-pumped infrared laser using transverse gas flow
    Patent number: 4651325
    Abstract: A transverse gas flow RF pumped waveguide laser has been developed utilizing RF discharge waveguide technology in several infrared lasers. Two potential applications have been identified; the pulsed chemical laser and the CW CO.sub.2 laser. In the chemical laser, the flowing gas device provides rapid gas replenishment to maintain high electrical efficiency at high repetition rates. In the CW CO.sub.2 laser, the flowing gas provides efficient cooling so that high output power per unit gain length can be achieved.
