Zn-diffused high power 650 nm AlGaInP/GaInP material with compressively strained multi-quantum-well active layer was fabricated. The zinc diffusion was used on the material facet in a sealed quartz tube. Photoluminescence spectra shows 175 meV blue-shift in the Zn diffusion area, which is transparent for 650 nm laser emission.
