The invention relates to a laser pulse transmission circuit. The laser pulse transmission circuit is provided with a gate chip, a low voltage differential voltage stabilizer, a driving integration chip and a field effect tube, wherein the two input ends of the gate chip are connected in parallel and then are connected with the output end of a triggering signal, and the output end of the gate chip is connected with the enabling end of the driving integration chip; the power source end of the gate chip passes through the low voltage differential voltage stabilizer and is connected with a power source, and the grounding end of the gate chip is grounded; the power source end of the driving integration chip is connected with the power source, the ENBA end of the driving integration chip is connected with VDD1, the AGND end and POND end are respectively grounded, and the two output ends of the driving integration chip are connected in parallel, and then are connected with a grid of the field effect tube through a resistor; a source of the field effect tube is grounded, and the grid of the field effect tube passes through a resistor, a transistor and the other transistor and is connected with a drain. The laser pulse transmission circuit has the advantage that when the laser tube transmits laser, the full-power transmission of laser power is realized.
