Second harmonic generation of swift carbon ion irradiated Nd:GdCOB waveguides

Opt Express. 2011 Jun 20;19(13):12490-5. doi: 10.1364/OE.19.012490.

Abstract

We report on the second harmonic generation at ~532 nm of optical waveguides in Nd:GdCOB produced by swift carbon ion irradiation. The fabricated waveguide shows good guiding property. Under pump of ~1064-nm fundamental light, the optical conversion efficiency of the frequency doubling is 0.48% W(-1) and 6.8% W(-1) for continuous wave and pulsed laser beams, respectively.
