Laser beam generating unit |
摘要 |
A laser beam generating unit has a semiconductor laser unit having a plurality of beam emitting portions located in the shape of a matrix, and a plurality of optical fibers for individually transmitting laser beam emitted from the beam emitting portions. An optical fiber bundle is formed by binding a plurality of the optical fibers on a side where laser beam emits, and laser beam is emitted through a taper adaptor provided on the side where laser beam emits. Then, laser beam can be transmitted by the optical fibers at a good condition, and can be collected by a beam transmitting path of the adaptor having the thinner diameter with high efficiency and the power density can be raised.
