<p><P>PROBLEM TO BE SOLVED: To provide an optical amplifying device which is small in size, enhanced in output, and easily made stable. <P>SOLUTION: The optical amplifying device 1A is equipped with an optical amplifying unit 10A, and an energy supplying unit 30. The optical amplifying unit 10A contains an optical amplifying medium 11 and a transparent medium 12. The energy supplying unit 30 supplies pumping energy (eg, pumping light) to the optical amplifying unit 11. The optical amplifying medium 11 receives the supplied pumping light, amplifies the pumping light, and outputs the amplified light. The transparent medium 12 transmits the amplified light of the optical amplifying medium 11 twice or more times. The transparent medium 12 is capable of, for example, propagating the amplified light inside in zigzags. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
