An ultrashort femto laser pulse system operates with pulse durations in the femtosecond range, enabling material interaction at extremely high peak power but minimal thermal load. Unlike conventional laser processes, this approach prevents melting, burr formation, and microcracks. The result is highly controlled material modification at micro- and nano-scale levels. These systems are engineered for both subtractive and surface-modifying processes, including micro-engraving, functional texturing, high-contrast marking, and laser-based polishing. Advanced motion control, beam shaping, and software-driven process optimisation ensure consistent results even on complex 3D geometries.

Cold Laser Processing with Minimal Thermal Impact

Ultrashort pulses ensure material removal or modification occurs before heat diffusion, eliminating thermal distortion and preserving mechanical properties.
