Femtosecond laser has the following three characteristics: firstly, the duration of femtosecond laser is extremely short, only a few femtoseconds, which is thousands of times shorter than the shortest pulse obtained by electronic methods, and is the shortest pulse that humans can obtain under experimental conditions. Secondly, femtosecond lasers have extremely high instantaneous power, reaching millions of gigawatts, which is hundreds of times more than the total power generation in the world. Once again, femtosecond lasers can focus into a spatial area smaller than the diameter of a hair, making the intensity of the electromagnetic field several times higher than the force exerted by the atomic nucleus on its surrounding electrons. Due to the extremely high peak power of femtosecond laser, after focusing, its intensity can reach the order of 1022W/cm2. Such intensity far exceeds the Coulomb field of internal atomic interactions, so femtosecond laser pulses can easily release electrons from atomic bonds, form plasma, and easily cause material dissociation.

In the field of microfabrication, due to its minimal impact on the surrounding material, it can be safely cut, drilled, engraved, and even applied in the photolithography process of integrated circuits.
