For a fast response -


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 ultra delivers <15 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 pump-probe spectroscopy. The repetition rate can also be stabilized to an external reference or other laser system.

Power Stability: RMS, measured over 24 hours after cold-start within operating temperature range.

Pulse Duration: Achieved with optional extra cavity compression.

Repetition Rate: accuracy +/- 100 KHz, other repetition rates available upon request.

Repetition rate must be selected at the time of order.

If required, the repetition rate can be locked to a suitable radiofrequency reference source.
