<P>PROBLEM TO BE SOLVED: To provide a laser treatment apparatus capable of achieving painless treatment with improved irradiation efficiency and achieving novel effects of the irradiation with the laser. <P>SOLUTION: The laser treatment apparatus includes a high-peak laser resonator 11 for the pulse irradiation with a laser beam 12 with the high peak output at 30W-90W; a discharge excitation power supply 21 to excite discharge of the high-peak laser resonator 11; a light guide path 14 for guiding the laser beam output from the high-peak laser resonator 11 to an irradiated body 17; a condensing lens 13 for condensing the laser beam 12 output from the high-peak laser resonator 11 into the light guide path 14; and a condition adjusting part 20 for adjusting conditions for laser beam irradiation patterns to irradiate the irradiated body 17. The oscillation cycle of the laser irradiation excitation pulse to irradiate the irradiated body 17 for adjusting the conditions by the condition adjusting part 20 is at least 50 μs and not more than 1000 μs, and the pulse width of the laser irradiation excitation pulse is at least 1% and not more than 30% of the pulse oscillation cycle. <P>COPYRIGHT: (C)2009,JPO&INPIT |
