Second-harmonic generation of a tunable continuous-wave CO2laser in orientation-patterned GaAs

Second-harmonic generation of a tunable continuous-wave CO2laser in orientation-patterned GaAs

Tunable, mid-infrared radiation was obtained by frequency doubling of a continuous-wave CO2 laser in orientation-patterned GaAs crystal. Active cooling of the crystal minimized pump-induced thermal effects, allowing generation of output powers exceeding 300 mW across the wavelength range of 4.63-4.7...

Zusammenfassung:Tunable, mid-infrared radiation was obtained by frequency doubling of a continuous-wave CO2 laser in orientation-patterned GaAs crystal. Active cooling of the crystal minimized pump-induced thermal effects, allowing generation of output powers exceeding 300 mW across the wavelength range of 4.63-4.78 mu m.
