Abstract
The amplifier achieved a record gain of 47dB, meanwhile the ASE has been effectively suppressed to -40 dB below the laser signal. It shows wide dynamic range and can be operated with input as low as 10pW. Experiments have been performed by applying this novel design in Er-doped fiber amplifies at 1.5um and Yb-doped amplifier at 1.0um wavelength ranges, with running conditions of cw, directly driven 2ns laser pulses, model-locked 10ps fiber lasers, and mode-locked, dispersion-compensated 100fs soliton fiber lasers. The amplifiers especially outperform the traditional fiber amplifiers when operating at lower repetition rates where the ASEs are strongly competing with stimulated emissions.
