Abstract
The present application discloses a laser emitting circuit and a LiDAR. The laser emitting circuit includes an energy charging circuit, an energy transfer circuit, and a plurality of energy release circuits. The plurality of energy release circuits are connected in parallel. The energy charging circuit is connected to the energy transfer circuit to store electrical energy. The energy transfer circuit is connected to the energy charging circuit and the plurality of energy release circuits to transfer the electrical energy stored in the energy charging circuit to the energy transfer circuit. The energy transfer circuit includes an energy storage capacitor and a floating-ground diode. Each energy release circuit is configured to drive a laser diode to emit light by using the electrical energy stored in the energy transfer circuit, and the energy release circuit includes an energy release switch element, the laser diode, and a clamping diode.
