<p>PROBLEM TO BE SOLVED: To provide a laser device for removing any complicate and dangerous work for exchanging a laser light source or the cause of failure, and for solving the problem of instability or large sealing due to spatial guided waves and a device to which this laser device is applied. SOLUTION: Plural optical fibers 15 for guiding output lights from a laser light source group 13 are fixed at prescribed positions with prescribed intervals at the input side of a switching connecting device 11, and one optical fiber 17 is arranged at the output side. This laser device is provided with a means for connecting the input side to the output side as necessary so that laser beams wave with arbitrary wavelength can be selected. Also, a controller 10 is connected so that the operation of the switching connecting device can be controlled, or that the sequence control of a switching sequence or a timing can be realized. The controller 10 with a built-in microcomputer or the like can realize the position control of the optical fiber at the output side, and hold the connection of the input side and output side in an optimal state.</p> |
