Abstract

In this work, we discuss methods to adjust the beam divergence of vertical-cavity surface-emitting lasers (VCSELs) by controlling the transversal lasing modes using different epitaxial designs. We show results of high power, multi-watt VCSEL arrays with emission cones ranging from 10° to 40°.
