Operation of transversely excited N2O lasers

摘要

An improved method and apparatus for producing high power, high efficiency pulsed TEA laser energy at N2O wavelengths by suppressing discharge arc formation with H2 or CO that is added to the N2O lasing medium. Energy loading levels up to in the range of 266 J/L atm are achieved with gas mixtures of N2 lasing mediums and H2 or CO additives comprising N2O:He:N2:H2::0.03:0.69:0.27:0.01 and N2O:He:N2:CO::0.03:0.66:0.26:0.05 mole fraction.
