Abstract
In this work we present a high-power laser source developed in Master Oscillator Power Amplifier (MOPA) configuration. Presented MOPA source consists of three amplifying stages: pre-amplifier based on erbium-doped fiber, medium-power stage based on double-clad Er/Yb co-doped fiber and the power stage, based on Er/Yb co-doped doubleclad LMA fiber. Whole system is set up in All-In-Fiber technique, without any bulk, free-space optical elements. It provides over 20W of output power in the eye-safe 1550 nm band.
