Abstract :
We have fabricated high-power bottom-emitting VCSELs for a wavelength of 990 nm with a record high maximum output power of 0.89 W. Favorable beam characteristics such as a circularly symmetric near-field pattern and low divergence far-field together with high power density of more than 1.1 kW/cm/sup 2/ allow for multimode fiber coupled power of more than 0.5 W. Further improved beam quality can be obtained applying an external reflector for higher order transverse mode filtering.
