21 February 2011 Frequency doubling of a CO2 laser using orientation patterned GaAs
Author Affiliations +
High efficiency second harmonic generation of a pulsed TEA CO2 laser operating at 9.569 μm was demonstrated in a quasi-phase-matched GaAs structure, 1.48 mm thick, 39.7 mm long and 8.3 mm wide, and having a grating period of 219.6 μm. The structure was grown by hydride vapor phase epitaxy and was dual-band anti-reflection coated on both entrance and exit surfaces. Energy of 1.2 mJ was obtained at 4.78 μm from single pass conversion with incident energy of 2.56 mJ.
