Abstract
An embodiment of this application discloses a laser emitting circuit and a LiDAR, and belongs to the field of the LiDAR. The structure of the laser emitting circuit is changed so that for the laser emitting circuit in an energy transfer stage, the energy transfer current from an energy storage element does not pass through a laser diode, and the laser diode is in a reverse-biased state relative to the energy transfer current. Therefore, the parasitic capacitance of an energy releasing switch element does not cause the laser diode to emit light in advance during an energy transfer charging process, which prevents the laser diode from emitting light at an unanticipated time, thereby solving the problem of laser leakage.
