Abstract
Chirped fiber gratings recently emerged as a new technology for dispersion compensation in communication systems.1 Here we investigate in-fiber chirped Bragg gratings as stretchers and compressors for distortionless amplification of femtosecond pulses in a fiber amplifier. The first all-fiber femtosecond chirped-pulse-amplification (CPA) system is demonstrated. It consists of a mode-locked fiber oscillator, an erbium-doped fiber amplifier, and an in-fiber stretcher and compressor, and it is pumped with a diode laser.
