Abstract :
The first all-semiconductor GaAs/AlGaAs vertical cavity laser incorporating wavelength resonant periodic gain layers grown by metalorganic chemical vapour deposition is reported. The optically pumped structure exhibits a threshold of 0.5 nJ at 852 nm for 720 nm pulsed excitation and energy conversion efficiencies up to approximately 6%. The output linewidth is \n\n\t\t
