nLIGHT, Inc., Vancouver,...

1. An apparatus, comprising:a semiconductor waveguide extending along a longitudinal axis and including a pumped first waveguide section and a second waveguide section, wherein a lateral refractive index difference defining the semiconductor waveguide is larger for the first waveguide section than for the second waveguide section; and
an output facet situated on the longitudinal axis of the semiconductor waveguide to emit a laser beam propagating in the semiconductor waveguide, wherein the first waveguide section is situated between the second waveguide section and the output facet and wherein the lateral refractive index difference suppresses emission of higher order transverse modes in the laser beam emitted by the output facet.

EYE-SAFE LIGHT SOURCE

SHARP KABUSHIKI KAISHA, ...

1. An eye-safe light source comprising:a substrate;
a semiconductor laser that emits laser light from a light emission end surface; and
a wire that is joined to the semiconductor laser,
wherein the semiconductor laser is joined to the substrate such that the laser light is emitted in a direction parallel to a reference surface of the substrate,
the substrate has a resin part,
the resin part includes a reflection surface that faces the light emission end surface and reflects the laser light,
a direction in which the wire extends when seen from a direction perpendicular to the reference surface is perpendicular to a direction of emission of the laser light from the light emission end surface,
the reflection surface is covered with metal,
the substrate includes a metal lead frame and a resin that at least partially covers the metal lead frame, and
the semiconductor laser is joined to the metal lead frame.
