Femtosecond lasers, a group of ultrafast lasers, are among the most advanced tools in precision manufacturing. Smartphone screensNikolajus Gavrilinas, the CEO of LITILIT, says that the high precision makes femtosecond lasers one of the few methods for manufacturing day-to-day electronics. For example, many screens and camera lenses of the latest smartphones are cut with a femtosecond laser. “Femtosecond lasers are used across electronics manufacturing because they can process delicate materials with extremely high precision and minimal heat damage. Now, as technology progresses, femtosecond lasers could extend to other fields of medicine.
