The invention discloses a laser obstacle removing system. The system comprises an unmanned aerial vehicle (1), a three-axis stable holder (2) arranged at the lower part of the unmanned aerial vehicle(1), a laser (3) arranged on the three-axis stable holder (2), and a first lens (4) arranged in front of the laser (3) and connected with the laser (3); the emission direction of the laser (3) is aligned with the center of the first lens (4); and in the horizontal direction, the first lens (4) covers the lower part of the three-axis stable holder (2) and the laser (3). According to the laser obstacle removing system, the three-axis stable holder is used for arranging the laser, so that the arrangement stability of the laser can be improved; and in addition, the light gathering capability of the laser can be improved through the first lens, so that the obstacle removing time is shortened, the laser can be prevented from being blocked by an obstacle, the working time is prolonged, and the failure rate is reduced.
