Femtosecond optical parametric oscillator Femtolock™ 2

Ti:sapphire

Femtolock™ 2 is a sub-100 fs jitter synchronization unit for Element™ 2 and Synergy™ ultrafast Ti:Sapphire oscillators. It allows locking of the round-trip frequency of oscillator pulses to a given reference RF-source. The use of multiple harmonics of the resonator round-trip frequency in combination with a simple and passively stable femtosecond laser resonator (based on Dispersive Mirror technology) enables low jitter levels. • Ultra-low timing jitter • Hands-free operation • Maximum flexibility • Long term stability • Synchronization to clock signals • ASOPS Maximum Flexibility Access to the loop filter settings allows the user to optimize the timing jitter and to adapt to different applications. Femtolock 2 enables synchronization of the laser’s repetition rate by locking on the fundamental input RF-frequency, on one of its higher harmonics or to easily switch between the two. Femtolock 2 can be custom designed to meet your specific requirements in terms of frequency and configuration. Maximum Stability The system is based on a combination of fast piezo translator(s) (PZT) and a wide range translation stage. This arrangement allows the Femtolock 2 to compensate for fast fluctuations (kHz), as well as for slow or medium long term drifts (e.g. temperature drifts). The unique configuration ensures resonance-free synchronization up to high frequencies and guarantees a long term drift-free operation.
