Giant-chirp fiber oscillators

摘要

Recent work has shown that stable, highly-chirped pulses can be generated by all-normal-dispersion fiber lasers. Pulses in the ～100-ps range but with bandwidth to support ～500-fs pulses are produced, with energies of tens of nanojoules and at repetition rates of 1 MHz and below. The chirped pulses can be compressed to near the transform limit. Lasers that produce pulses with such giant chirp should greatly simplify chirped-pulse fiber amplifiers. After a brief review of fiber lasers based on dissipative solitons, recent developments will be summarized.
