摘要

A femtosecond laser generator according to an embodiment of the present invention includes a pulse generator that converts a continuous wave laser into an optical pulse train, a burst generator that separates the optical pulse train into a plurality of burst pulses, and amplifies the plurality of burst pulses to expand the spectrum a pulse amplification and spectrum extension unit, and a pulse compression unit for compressing the plurality of amplified burst pulses to generate a femtosecond laser having a pulse width of 1 picosecond (10 -12 s) or less.
