摘要：
We report a compact all-diode-laser-pumped erbium-doped fiber system consisting of an environmentally stable Kerr-type mode-locked fiber oscillator and a fiber amplifier. High-repetition-rate (38 MHz) 200-fs-duration pulses were amplified to as much as 3 nJ of energy and 150 mW of average power. Amplification of unstretched and stretched pulses was studied. Using chirped-pulse amplification, we obtained clean pedestal-free 420-fs pulses. Amplification of unstretched pulses produced 84-fs pulses with a broad pedestal.
