Abstract: The present disclosure provides a laser emitting module and a LiDAR apparatus. The laser emitting module includes at least two groups of laser emitting circuits. Each group of the laser emitting circuits includes one charging energy storage circuit and at least one energy releasing circuit. The energy releasing circuit includes an energy releasing switch and at least one laser. The energy releasing switch is turned on to drive at least one laser to work correspondingly. The charging energy storage circuit and the energy releasing circuit are arranged one-to-one or one-to-multiple. Any two adjacent emissions correspond to different groups of the laser emitting circuits.
