The Laser Quantum gecco is a femtosecond laser with an exceptionally robust mechanical design in a sealed housing comprising a proprietary mechanism to self-start, monitor and maintain its mode-locking. It is available in a choice of pulse durations, powers and repetition rates to suit many applications.

"The Gecco works great as a seed laser for our 25 fs kHz amplifier system. We are very happy to have this set-and-forget femtosecond laser delivering reliable and reproducible performance every day."
