    摘要： A light emitting device includes a base, a frame, first and second semiconductor laser elements, one or more light-reflective members, and wires. The frame part has first inner lateral surfaces, second inner lateral surfaces, a first and second step-parts respectively formed along the second inner lateral surfaces. The wires are bonded to an upper surface of the first step-part or an upper surface of the second step-part. The first semiconductor laser element is disposed closer to the first step-part.
    The second semiconductor laser element is disposed closer to the second step-part. All of the wires that electrically connect the first semiconductor laser element to the frame part are not bonded to the upper surface of the second step-part. All of the wires that electrically connect the second semiconductor laser element to the frame part are not bonded to the upper surface of the first step-part.

    摘要： A laser diode driver includes a clock terminal to receive a clock signal, configuration terminals to receive configuration data, drive terminals, and charging terminals. A first charging terminal is operable to charge a source capacitor of a resonant circuit that includes the source capacitor, an inductor, and a bypass capacitor. Each drive terminal is operable to be directly electrically connected to an anode or cathode of a laser diode or to ground. A mode, output selection, and grouping of drive signals that are delivered to the laser diodes are configured based on the configuration data. The laser diode driver is operable to control a current flow through the resonant circuit to produce high-current pulses through the laser diodes, the high-current pulses corresponding to a peak current of a resonant waveform developed at respective anodes of the laser diodes, a timing of the high-current pulses being synchronized using the clock signal.

    摘要： A light-emitting element array according to the present technology includes: a light-emitting element group; a first wire; and a second wire. The light-emitting element group includes a plurality of first light-emitting elements and a plurality of second light-emitting elements that are arrayed in a planar manner to form a light-emitting element surface. The first wire extends in a direction parallel to the light-emitting element surface, has a region overlapping with the plurality of first light-emitting elements and a region overlapping with the plurality of second light-emitting elements as viewed from a direction perpendicular to the light-emitting element surface, is electrically connected to the plurality of first light-emitting elements, and is not electrically connected to the plurality of second light-emitting elements. The second wire extends in a direction parallel to the light-emitting element surface, has a region overlapping with the plurality of first light-emitting elements and a region overlapping with the plurality of second light-emitting elements as viewed from a direction perpendicular to the light-emitting element surface, is electrically connected to the plurality of second light-emitting elements, and is not electrically connected to the plurality of first light-emitting elements.

    摘要： A laser emitting apparatus includes: a drive assembly, a laser emitter, an energy storage module, and a circuit board. The laser emitter is a laser emitter die. An input end of the laser emitter is electrically connected to the energy storage module, and an output end is electrically connected to the drive assembly. The energy storage module is used to generate electrical signals required for driving the laser emitter. The drive assembly is used to output the driving signal to control the energy storage module and the external power supply to output the electrical signal to the laser emitter, so as to enable the laser emitter to emit laser. The drive assembly, the laser emitter, and the energy storage module are fixed on the circuit board, and a ground layer is arranged in the circuit board.
