Abstract

An InGaAs/GaAs vertical-cavity surface-emitting laser (VCSEL) with resonant periodic gain (RPG) was optically pumped using a pulsed dye laser at 760 nm with 500 ns pulse width. Output pulse energies at 918 nm in excess of 20 mJ were observed from a 3.3 mm diameter lasing spot. This corresponds to an efficiency of greater than 20%. Approximate area scaling of threshold and maximum available output power (limited by the optical pumping damage threshold) was demonstrated.
