High-power chirped-pulse all-fiber amplification system based on large-mode-area fiber gratings.
We describe the fabrication of chirped gratings in a specially developed photosensitive large-mode-area fiber and report the use of these components in a picosecond all-fiber chirped-pulse-amplification circuit. We demonstrate the generation of microjoule energy pulses with peak powers in excess of 500 kW, which we believe to be a record peak power from an all-fiber system.
