The utility model discloses a laser remote dynamic focusing system. The device comprises a focusing system, a CCD camera, a thermal infrared imager, a laser, a control box and a display, the focusingsystem comprises a collimating mirror, a first reflecting mirror, a second reflecting mirror, a first imaging mirror, a second imaging mirror and a focusing mirror. Wherein the first reflecting mirroris located between the collimating mirror and the focusing mirror, the second reflecting mirror is parallel to the first reflecting mirror, the first imaging mirror is located right in front of the CCD camera lens, the second imaging mirror is located right in front of the thermal infrared imager lens, and the axis of the second imaging mirror is perpendicular to the axis of the first imaging mirror. According to the utility model, the thermal infrared imager is adopted to feed back the temperature at the laser focus in real time, so that the laser is prevented from damaging cables or other devices, and meanwhile, the
