We report 3kW test data of Single-Mode (SM) Ytterbium-doped fiber amplifier with diffraction-limited divergence for narrow linewidth seed sources in compact modular package with all-fiber format. Measured M2 values of output beam in full power range are < 1.1. The fiber amplifier has been pumped by direct laser diodes and has 3m output delivery cable terminated with IPG connector. The fiber amplifier in modular package has ≥ 40% wall-plug efficiency and 15nm spectral bandwidth in 1055-1070nm wavelength range. The amplifier operates up to 3kW at linewidths of 60GHz and 30GHz with polarized and depolarized seed sources respectively. The amplifier data and non-linear SBS, SRS and MI effects are discussed for different input linewidth and test conditions.
