5.5 W monolitic single-mode fiber laser and amplifier operating near 976 nm

An all-glass Yb-doped single-mode fiber laser and amplifier with output power of more than 5 W near 977 nm have been realized. Both laser and amplifier were based on a specially developed photodarking-free Yb-doped fibers with increased core-to-clad diameter ratio (up to 0.31).
