Abstract

An electric-pulse-driven super-luminescent diode laser generating 1064 nm wavelength with 37 nm-bandwidth, several nanoseconds pulses at 20 Hz repetition rate was used to seed an amplifier cascade featuring a 30 μm core Yb-doped fiber as the final power amplifier. From this amplifier cascade, we obtained pulse energy from 1.0 to 1.5 mJ depending on different pulse durations with beam quality of M ² 1.7; the highest peak power in excess of 545 kW and 10 nm-bandwidth centered at 1064 nm, which is the widest bandwidth of pulsed Yb-doped millijoule fiber amplifier to our knowledge. Moreover, this allfiber structure has application to many fields.
