Visible emitting all-AlGaAs vertical-cavity surface-emitting lasers (VCSELs) have been produced by metal organic vapor phase epitaxy (MOVPE) using ultra-high purity source reagents. Lasing was obtained at wavelengths in the range 683-713 nm using four 45 /spl Aring/ Al/sub 0.18/Ga/sub 0.82/As quantu...
