gecco – Ultrafast Femtosecond Laser

The gecco femtosecond oscillators are based on an exceptionally robust mechanical design in a sealed housing comprising proprietary mechanisms to self-start, monitor and maintain its mode-lock. The gecco one delivers <20 fs pulse duration at >600 mW output power with choice of repetition rate and integrated pump laser to suit many different applications such as amplifier seeding or microscopy. The repetition rate can also be stabilized to an external reference or other laser system.
