Ngr. Broderick et al., High-power chirped-pulse all-fiber amplification system based on large-mode-area fiber gratings, OPTICS LETT, 24(8), 1999, pp. 566-568
We describe the fabrication of chirped gratings in a specially developed ph
otosensitive large-mode-area fiber and report the use of these components i
n a picosecond all-fiber chirped-pulse-amplification circuit. We demonstrat
e 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
