PURPOSE:To easily obtain laser light suitable to medical treatment at lot cost by mixing different kinds of laser light beams which are induced and emitted by two independent laser devices. CONSTITUTION:An articulated manipulator induces and emits CO2 laser light L1 with high parallelism, which passes through the 1st front lens 1 to obtain a constant spread angle in its beam direction and reaches and passed through a dichroic mirror 3. Then, YAG laser light L2 emitted from an end of an fiber able 5, on the other hand, passes through the 2nd front lens 2a and is reflected by a mirror 2b to reaches the tip direction of the probe LA 1 of the dichroic mixing mirror 3, so that the light beam is reflected by its mirror surface toward a condenser lens 4. Then, the CO2 laser light L1 transmitted through the dichroic mixing mirror 3 almost in the center and the YAG laser light L2 reflected at almost the same center point with the CO2 laser light L1 are mixed coaxially to reach the condenser lens 4 as mixed light beams L1+L2. |
