PURPOSE:To obtain a laser device for treatment on satisfactory operability, which can easily execute the cooling of a part to be irradiated with a laser and a nearby part, by arranging a cooling part, which has a laser transmissible part and utilizes an electronic cooling element, on the tip surface of a hand piece. CONSTITUTION:A contact 24a is connected by pushing a power source switch 24 and a voltage is applied to an electronic cooling element 22. Then, the electronic cooling element 22 is operated and heat is removed from a cooling surface 22a and radiated from a radiating surface 22b. In order to easily execute the radiation, a joint part 21a of the electronic cooling element 22 in a holding part 21 is composed of metal such as aluminum and copper, etc., for example, whose thermal conductivity is satisfactory. Then, the heat is easily radiated through the holding part 21 to an external part. When a laser device is used, the holding part 21 is grasped and a cooling side surface 22a of the electronic cooling element 22 is abutted on the laser irradiating part. Then, the power source switch 24 is pushed and the electronic cooling element 22 is operated. After that, the temperature of the laser irradiating part is cooled and displayed through a temperature measuring element 25 to a temperature display 26. Then, the cooling is executed with monitoring the degree of the cooling for the laser irradiating part. |
