Abstract
The present application discloses a laser emitting circuit and a LiDAR. In a one-driving-multiple emitting circuit, in an energy storage stage, a power supply stores energy for an energy storage element of the energy storage circuit, and a laser diode does not emit light. In an energy transfer stage, by setting a floating-ground diode D0, an energy charging current passes through an energy storage capacitor C2, the floating-ground diode D0 and the ground to form a loop. In an energy release stage, when the energy release switch element is in an off state, the energy release circuit where the energy release switch element is located is not the lowest impedance loop. A laser diode in the energy release circuit where the energy release switch element is located does not emit light.
