Why Femtosecond Laser Micromachining Is A Preferred Choice Over Other Micromachining Methods

Laserod Incorporated was established by Rod Waters in the mid 1990s, succeeding Florod, an organization built up by Waters and an accomplice during the 1970s.

Femtosecond laser solutions, which include micromachining, are constantly growing and evolving across various business areas. Ultrafast lasers are predominantly used in applications where the requisite HAZ and efficiency are not achieved by traditional CW, long-pulsed fiber, nanosecond, and picosecond laser systems.

femtosecond laser represents 10 to the −15 of a second, which is one-millionth of a billionth of a second. At given pulse energy, the laser's peak power increases as the pulse's length become shorter. Hence, femtosecond lasers have a much higher peak power than longer pulsed picoseconds, millisecond or nanosecond pulsed lasers.

Since total energy is transmitted to the substance and less is drawn into heating the material, these higher peak powers result in higher removal rates in a material. These femtosecond lasers' high peak power, sometimes several-MW, disrupts the atoms and electrons in the material, resulting in what is known as a "Coulomb explosion." A Coulomb explosion is an-alternative cold processing to traditional thermal ablation used by longer pulsed lasers.

Ablation is a thermal mechanism that relies on molecules and atoms local heating, melting, and vaporizing. For some laser applications, ablation can be harmful. It usually creates unnecessary HAZ, recast, and burs, all of which have adverse heat effects that make cold ablation a better option.
