Abstract: This application discloses an anode addressing drive circuit, an addressable drive circuit, and a laser emission circuit. The anode addressing drive circuit includes: an anode addressing switch circuit, including an anode addressing switch element, where a first end is connected to an emission power supply, a second end of the anode addressing switch element is connected to an anode energy storage circuit, an anode addressing enabling end of the anode addressing switch element receives an anode addressing signal, and the anode addressing switch element is turned on or off under the control of the anode addressing signal; and an anode energy storage circuit, including an anode energy storage element and a current limiting element, where the anode energy storage element is configured to be charged through an output current of the emission power supply when the anode addressing switch circuit is turned on, and the current limiting element is configured to limit a current for charging the anode energy storage element.
