<P>PROBLEM TO BE SOLVED: To provide a laser treatment apparatus that can stably output laser light ranging from a high output to a low output without causing deviation of the laser optical axis at the outgoing end. <P>SOLUTION: The laser treatment apparatus irradiating a treated site with laser light from a treatment laser source is composed of a plurality of optical elements including at least one beam splitter obliquely provided, and has a laser light damping means in which the optical elements are regulated to ensure that the axis of laser is constant at a final optical element end, a driving means to insert and remove the laser light damping means into and from the optical path and a control means to control the action of the driving means on the basis of a signal of the laser irradiation conditions set. <P>COPYRIGHT: (C)2004,JPO |
