Narrow Linewidth 49 W All Fiber Linearly Polarized Picosecond Laser Operating at 1016 nm
Abstract
An all fiber linearly polarized narrow linewidth pulsed fiber laser operating at 1016 nm is demonstrated in a master oscillator power amplification (MOPA) configuration. Core-pumped double cladding ytterbium-doped large mode area fiber amplifiers are proposed as the pre-amplifiers to reduce the nonlinearity and the ASE. The laser exhibits 48.6 W average output power, ∼18 kW peak power, and 0.28 nm linewidth.
