Abstract: A laser module is provided and includes a laser unit, a focusing lens, an electric device, and a temperature control device. The laser unit is configured to emit a laser light. The focusing lens corresponds in position to the laser unit, and the focusing lens is configured to converge the laser light emitted from the laser unit so as to outwardly output the laser light. The electric device includes a focusing ring, a voice coil motor, and a motor base. The voice coil motor is configured to drive and move the focusing lens in a straight line toward or away from the laser unit with the focusing ring. The temperature control device is mounted on the laser unit and includes a thermoelectric cooling module and a thermistor. The thermoelectric cooling module is configured to cooperate with the thermistor to adjust a working temperature of the laser unit.
