A surface-emitting laser (see Fig. 2, Character 10), in which light is emitted vertically at one end from a near 45° angled facet, includes a second end (see Fig. 2, Character 28) having a perpendicular facet from which light is emitted horizontally, for monitoring. The surface-emitting laser (see Fig. 2, Character 10) comprises a divergence-compensating lens (see Fig. 21, Character 282) on the surface above the near 45°angled facet. |
