Claim 10:
11. A system for use in mobile machine applications, comprising:
at least one processor coupled to a power source and configured to supply power to a driver to generate a first driving current and a second driving current;
a gallium and nitrogen containing laser diode configured to be driven by the first driving current to emit a first light with a first peak wavelength in a violet or blue wavelength range;
a sensing laser diode configured to be driven by the second driving current to emit a second light with a second peak wavelength in an infrared (IR) wavelength range;
the at least one processor configured to provide a modulated driving current to the sensing laser diode, the modulated driving current configured to generate a pulse of IR sensing light emitting light from the sensing laser diode;
a wavelength conversion member configured to receive at least partially the first light traveling along a first path; the first light incident on a surface of the wavelength conversion member and forming an excitation spot;
the wavelength conversion member configured to at least partially absorb the first light and reemit a third light with a third peak wavelength that is longer than the first peak wavelength, the third light being combined with at least partially the first light to yield a white light emission, wherein the system is configured to at least one of collimate, steer, or project a first beam of the white light emission for illuminating one or more remote objects, and to project a second beam of the IR sensing light with the second peak wavelength for sensing one or more remote objects and/or surroundings of the one or more remote objects; and
a detector configured to detect reflected signals of the IR sensing light for sensing the one or more remote objects.
