DATA SHEET FLS v1.2017 Cycle GmbH • Hamburg • Germany www.cyclelasers.com [email protected] Fiber Link Stabilizer APPLICATION Time of flight stabilization of fiber timing links DESCRIPTION The fully-automated FLS consists of a fiber link, a balanced optical cross-correlator, and all the other necessary actuators, fiber components, and control elements to support a fully-automated timing- stabilized fiber link. It preserves the low noise properties of the master laser during the delivery of the timing signal to remote locations by time-of-flight cross-correlation, resulting in market-leading low-drift and low-jitter timing distribution. SPECIFICATIONS Parameter Value Unit Comment Timing jitter 1 <5 fs RMS Within 35 μHz - 1 MHz bandwidth Timing resolution < 0.5 fs Integrated detector noise floor within 10 kHz bandwidth Fiber link length 2 < 10 km Fiber type SMF / PM With FC or SC connector Fiber link output power > 10 mW Average Optical wavelength 1550 ± 50 nm Operating at pulsed mode Pulse repetition rate < 500 MHz Tailored for the frequency of interest Integrated feedback included Optimized PID parameters Control system interfaces included Available in Epics, Tango… Auto lock included Dimensions BOC: 362mm x 109mm x 65mm + Optical Delay Line: 350mm x 120mm x 52mm Weight BOC: 3kg + Delay Line: 3kg 1 Specified for a 150m link, with 5˚C peak-to-peak environment temperature fluctuation. 2 Performance specifications for a 150 m link. Customized fiber lengths available.
