1. A LIDAR system comprising:

  • a power source;

    a processor coupled to the power source and configured to supply power to a driver to generate a first driving current and a second driving current including modulation signals based on input data from an external source;

    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;

    a sensing laser diode configured to be driven by the second driving current to emit a second light with a second peak wavelength configured to be a sensing light signal;

    a wavelength conversion member configured to receive at least partially the first light to 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 and configured to pass, scatter, or reflect the second light substantially without absorption;

    one or more optical elements coupled to the wavelength conversion member to receive the white light and to collimate, steer, and project a first beam of the white light for illuminating one or more remote objects, and to receive the second light to project a second beam of the sensing light signal centered with the second peak wavelength for mapping an area including the one or more remote objects and their surroundings; and

    a detector configured to detect reflected signals of the sensing light signal for mapping the one or more remote objects.
