Title:

OPTICAL FIBER-BASED HIGH-REPETITION-RATE FEMTOSECOND LASER GENERATOR AND LASER PROCESSING SYSTEM COMPRISING SAME

Document Type and Number:

WIPO Patent Application WO/2021/182839

Kind Code:

A1

Abstract:

A femtosecond laser generator according to an embodiment of the present invention comprises: a pulse generation unit for converting a continuous-wave laser into an optical pulse train; a burst generation unit for dividing the optical pulse train into multiple burst pulses; a pulse amplification and spectrum expansion unit for amplifying the multiple burst pulses and thereby expanding a spectrum; and a pulse compression unit for compressing the multiple amplified burst pulses and thereby generating a femtosecond laser having a pulse width of 1 picosecond (10-12s) or lower.
