ABSTRACT:
A surface-emitting laser, in which light is emitted vertically at one end from a near 45°-angled facet, includes a second end having a perpendicular facet from which light is emitted horizontally, for monitoring. The surface-emitting laser comprises a divergence-compensating lens on the surface above the near 45°-angled facet.
