CO sub(2) laser-fabricated cladding light strippers for high-power fiber lasers and amplifiers

We present and characterize a simple CO sub(2) laser processing technique for the fabrication of compact all-glass optical fiber cladding light strippers. We investigate the cladding light loss as a function of radiation angle of incidence and demonstrate devices in a 400 [mu]m diameter fiber with c...

Description
Summary:We present and characterize a simple CO sub(2) laser processing technique for the fabrication of compact all-glass optical fiber cladding light strippers. We investigate the cladding light loss as a function of radiation angle of incidence and demonstrate devices in a 400 [mu]m diameter fiber with cladding losses of greater than 20 dB for a 7 cm device length. The core losses are also measured giving a loss of
