摘要：
We report high power and high efficiency operation of a vertical cavity surface emitting GaAs laser in an external cavity. The maximum cw output power from the fundamental TEM00 mode was 700 mW at a temperature of 77 K when pumped by a cw krypton-ion laser with 1.8 W pump power. We obtained an absolute quantum efficiency (pump photons to lasing photons) of 44%, and a differential efficiency above threshold of 58%.
