A laser pointer touch system, which includes an infrared touch screen, a laser pointer, and a calculation module. The infrared touch screen is connected to the calculation module. The infrared touch screen includes a circuit board frame. The circuit board is on the display of the infrared touch screen. Four sides are provided with X-axis transmitting tubes, X-axis receiving tubes, Y-axis transmitting tubes, and Y-axis receiving tubes, which correspondingly generate an infrared matrix. The infrared rays emitted by the X-axis transmitting tube and the Y-axis transmitting tube are pulsed infrared rays. The laser light emitted by the laser pointer is a pulsed laser. After the laser is superimposed on the pulsed infrared light emitted by the X-axis emission tube and the Y-axis emission tube of the infrared touch screen, the minimum intensity of the infrared pulse is calculated, and then it is judged that this is the touched place.
