PURPOSE:To prevent a casual accident by a laser beam while exhibiting the effectiveness of a laser treatment by disposing a semiconductor laser for varying the laser beam with low outputs of a specific range according to treatment purposes and adjusting the focal length of the condensed laser beam. CONSTITUTION:A printed board 26 packaged with various kinds of semiconductor elements for driving the semiconductor laser 8 is disposed at a laser probe 2 of the laser treatment device. In the meantime, a connector 27 for connection is packaged via a wiring cord 3 at this printed board 26 and a laser generation control circuit 9 for regulating the output of the laser beam is packaged at the board. A focus changeover and display switch circuit 11 is packaged to the printed board 26 and is connected to a focus changeover lever 35'. Further, a condenser lens system 40 is disposed right under the semiconductor laser 8 and houses plural condenser lenses 46, 47 into a lens housing cylinder 41 via spacers 48. The output of the laser beam of the semiconductor laser 8 is varied in a range of 1 to <=10mW according to the treatment purposes. |
