Abstract
Cascaded second-harmonic and sum-frequency generation were used to obtain the third harmonic of a laser in a single quasi-phase-matched GaAs crystal. Both continuous-wave and pulsed regimes with a single-pass configuration were studied. The continuous case confirmed the good capability of the GaAs stack to bear high average power density. In the pulsed regime a 0.66% peak power conversion efficiency was achieved for the third harmonic when the laser was pumping at , in fair agreement with theoretical predictions.
