Femtosecond laser micromachining (also known as femto laser cutting or femtosecond laser drilling) is a laser-based process that uses pulses so short they avoid heat transfer to the surrounding material. This is especially useful for precision components in heat-sensitive applications like medical implants, microelectronics, or aerospace components.

Imagine trying to cut an intricate design into tissue paper without burning or tearing it—femtosecond lasers offer that level of finesse, but for materials like titanium, polymers, and even precious metals. The laser pulse vaporizes material on contact, without friction, heat, or mechanical stress. This makes it ideal for achieving burr-free edges, tight tolerances, and ultra-clean surfaces.

Modern manufacturing increasingly requires features below 25 microns in diameter or width, with consistent results across high-volume runs. Femtosecond laser machining allows engineers to push the limits of design while maintaining reliability, precision, and repeatability—especially in regulated industries.
