OPTICAL FIBER LASER RESONATOR |
摘要 |
PURPOSE: An optical fiber laser resonator is provided, which is used as a pumping source of a Tm-doped fiber amplifier of a non-silica family. CONSTITUTION: The first optical fiber(20) is connected to a laser diode(10) by a pig tailed form, and the second optical fiber(40) is connected by a different structure from the first optical fiber. The third optical fiber(31) consists of a cladding(42) and a core(41) where a grating is engraved and is configured to connect both ends of the first and second optical fibers by a tapering method. The first optical fiber is an SMA cable, the second optical fiber is a dual clad fiber which consists of a Yb-doped core and a cladding. GeO2 is doped in a core where the grating of the third optical fiber is engraved. A silica(32) as a packing means is configured such that an air gap is formed at the outside of the third optical fiber so that light passing through the cladding of the third optical fiber progresses smoothly.
