Abstract
We report on the fabrication and characterization of 5-mm-long quasi-phase-matched diffusion-bonded GaAs crystals designed for frequency doubling of a laser. Second-harmonic generation of a pulsed laser yielded up to 24% peak power efficiency at . Tunability and laser damage threshold are also investigated.
