Femtosecond Laser Processing in the Medical Device Industry

Femtosecond Basics.. Femtosecond light pulses are ultra-short pulses (USPs).. One fs equals 10-15 seconds, and as a calibration point, a 300-fs pulse equates to a physical length of pulse of only 90 micrometers.. Because there is no thermal processing as there would be in nanosecond (ns) pulses, USPs have many advantages: No heat impact—no ..
