FAS Series High-Repetition-Rate Fiber Femtosecond Lasers are our fully all-fiber, industrial-grade sources, built on a proprietary femtosecond seed and advanced amplification technology. Thanks to their all-fiber architecture, the FAS series delivers outstanding beam quality, a compact footprint, and rock-solid reliability.

With a broad power range (5 W–100 W), pulse widths tunable from 100 fs to 350 fs, and repetition rates up to 80 MHz, the FAS lasers meet the most demanding industrial and scientific applications. They achieve power stability as low as < 0.1 % rms (for outputs < 10 W) and can be equipped with SHG/THG modules for extended wavelength coverage—ideal for spectroscopy, precision micromachining, fluorescence imaging, and more.
