Abstract: A laser transmit module includes a capacitor, a laser transmitter, and a field effect transistor. The capacitor is configured to supply power to the laser transmitter. The field effect transistor is configured to control the laser transmitter to be turned on. The capacitor, the laser transmitter, and the field effect transistor are interconnected through conductive pins to form a laser transmission loop. Loop inductance generated by the laser transmission loop affects a pulse peak value of a laser pulse transmitted by the laser transmitter, thereby affecting a detection distance of the laser pulse. Therefore, the laser transmission loop is formed through a direct connection between the conductive pins of the capacitor, the laser transmitter, and the field effect transistor, to reduce distances between the components and reduce an area of the formed laser transmission loop, so as to increase the detection distance of the laser transmit module.
