Short wavelength (699 nm) electrically pumped vertical-cavity surface-emitting lasers

Room-temperature lasing has been achieved in vertical-cavity surface-emitting laser structures for wavelengths as short as 699 nm under pulsed electrical excitation. The molecular beam epitaxially grown structures have p- and n-type semiconductor quarter wave mirror stacks enclosing an active region containing a short period GaAs-AlAs superlattice.<
