Femtosecond lasers are increasingly utilised in laser material processing applications that require high precision and minimal material collateral damage. The ultrashort pulses, typically ranging from 30 fs to 800 fs (x10-15 s), minimise the laser-material interaction time which is advantageous for a number of reasons including a reduced thermal impact on the material. Recently  the development of high repetition rate diode-pumped femtosecond lasers has increased the viability of using femtosecond lasers for non-niche industrial applications in laser material processing.

The Amplitude Systemes s-Pulse HP is a Diode Pumped Femtosecond based on Ytterbium crystal technology.  The laser offers high beam quality, high energy, short pulse duration combined with a high pulse  repetition rate.
