It has high accuracy, low damages and other advantages conventional laser machining could not compare with. This paper describes these characteristics by comparing the basic principle and mechanism for the interaction between femtosecond laser pulses and the long pulses. Also we give some advanced applications of femtosecond laser pulses in micro-machining, structural processing, photonic devices manufacture, 3-D data storage, medical and bio-engineering, which shows its bright future in industry, micro-electronics, optical communication, optical information and life sciences.
