New Material for High Average Power Infrared Generation: QPM-DB GaAs

Abstract

We are investigating quasi-phase-matched diffusion-bonded (QPM-DB) gaAs for nonlinear infrared applications. We have fabricated diffusion-bonded stacks of up to nine layers, which we have used to demonstrate quasi-phase- matched second-harmonic generation pumped by 10.6-micrometers CO2 laser output. Preliminary optical damage tests of diffusion-bonded-stacked GaAs indicate a power handling capability in excess of other currently available nonlinear infrared materials. Numerical calculations modeling nonlinear frequency conversion and projectioned device performance are included in this report.
