Claim 0:
1. 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 or a sequence of pulses of IR sensing light emitted 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 mapping an area including the one or more remote objects and surroundings of the one or more remote objects; and
a detector configured to detect reflected signals of the IR sensing light for mapping the one or more remote objects.
