Abstract
We have observed quasiphase-matched second-harmonic generation in the refle ction geometry from GaAs/AlAs multilayers. By using GaAs/AlGaAs multilayers and Fresnel reflection as a cavity, we have also achieved cavity-enhanced nonphase-matched second-harmonic generation from GaAs/AlAs multilayers. The linewidth for the first order reflection-second-harmonic generation is lim ited only by wave-vector mismatch. In addition, we have demonstrated two-or der-of-magnitude enhancement on the conversion efficiency by using the cavi ty. (C) 2001 American Institute of Physics.
