OPTICAL FIBER LASER

摘要

The present invention relates to an optical fiber laser comprising: a pumping part which generates pumping light; an optical fiber oscillating part which comprises optical fibers which advance pumping light and oscillate laser light generated by absorbing the energy; and an optical fiber laser which comprises a vertical mode determination oscillating part including a first reflecting part which transmits a part of the laser light oscillated in an optical fiber and a second reflecting part which reflects optical signals introduced from the first reflecting part.
