Abstract :
Summary form only given. GaAs and AlGaAs have very large second-order susceptibilities. To achieve efficient frequency conversion, multilayers have been used to achieve, quasi-phase matching (QPM). Our investigation of the reflection-SHG from multilayers serves as a first step towards eventual applications of GaAs/AlGaAs multilayers for generating and amplifying mid-IR waves based on a novel configuration.
