PURPOSE:To provide the laser treating device having excellent operability by controlling a supply system for fluid, such as water or air used for a laser hand piece. CONSTITUTION:An exit end face 61 of a fiber 60 for transmission and an incident end face 11 of a fiber probe 1 are respectively provided with air chambers and are isolated water-tightly by a light guiding shielding plate 7. Air feed pipes 72, 75, 78 from respectively individually retreated air sources are connected to the air chamber 71 on the fiber side for transmission and the probe side air chamber 70 in such a manner that the air can be sent. A fiber protective pipe 2 inserted with the probe 1 is mounted to the front end of the hand piece and the spacing therebetween is connected to a water feed pipe 52 in such a manner that water can be supplied. A controller 14 which controls the stop valve of the water feed pipe 52 and a laser oscillator by input of an irradiation start switch SW 2, controls the stop valve of the air feed pipe for feeding the air to the air chamber 70 by input of an irradiation prepn. switch SW 1 and controls the air valve for mixing the air into the water feed pipe 52 by a spray switch is provided. |
