Abstract:
1. A laser optical apparatus, comprising: a first optical fiber; a second optical fiber; a plurality of first fine optical fibers having a first end portion and a second end portion, the first end portion of the plurality of first fine optical fibers being coupled to an end portion of the first optical fiber; a plurality of second fine optical fibers having a first end portion and a second end portion, the first end portion of the plurality of second fine optical fibers being coupled to an end portion of the second optical fiber, the second end portion of the plurality of second fine optical fibers being spaced from the second end portion of the plurality of first fine optical fibers without coupling to the second end portion of the plurality of first fine optical fibers; and a multichannel connector arranged to fix the plurality of first fine optical fibers and the plurality of second fine optical fibers, wherein the plurality of first fine optical fibers are symmetrically opposite the corresponding plurality of second fine optical fibers, and wherein lengths of the plurality of first fine optical fibers are different from one another and lengths of the plurality of second fine optical fibers are different from one another so that the plurality of first fine optical fibers transmit optical beams having changed phases to the plurality of second fine optical fibers; wherein the multichannel connector includes a fixing unit configured to fix the first and second fine optical fibers, the fixing unit comprising a transparent crystalline material; and wherein the first optical fiber and the second optical fiber have a diameter of 1 mm-3 mm.
