摘要：

Visible emitting all-AlGaAs vertical-cavity surface-emitting lasers (VCSEL's) 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 Angstrom Al0.18Ga0.82As quantum wells in the active region, At room temperature, a minimum threshold current density of 3.8 kA.cm(-2) was measured for a wavelength of 692 mn; this is the lowest value for an all-AlGaAs vertical-cavity laser operating at this wavelength, Growth of the epitaxial mirrors at 5.2 mu m/h(-1) results in a total growth time of only two and a bah hours.
