1550nm Ultrafast Optical Clocks
PriTel’s UOC Series of Ultrafast Optical Clocks are easy-to use actively-mode locked fiber lasers that provide high pulse repetition frequencies and high average output powers for 1550 nm time-division multiplexed communications R&D. The UOC can be used as a source for Solitons, RZ Optical Pulses and Optical Clocks

Tunable Pulse Repetition Rate
For fine alignment of the pulsed laser source to the experimental application, the UOC is continuously adjustable without gaps for repetition rates ≥9 GHz. For example, the UOC can be tuned precisely to the OC-192 standard, 9.95328 GHz.
Quick-Change of Pulse width
The UOC Series has always offered user flexibility in tuning operating wavelength and pulse-repetition frequency. PriTel's Quick-Change Pulsewidth feature, standard on all UOC models, enables the user to change the operating pulsewidth of the UOC within minutes just by replacing a self-aligning cartridge.
Quick-Change Filter Cartridges are available in four standard operating pulsewidths (10 ps, 5 ps, 2.5 ps, and 1.6 ps). A kit of all four standard cartridges is available at a discount. Please inquire about cartridges for special pulsewidths.
Quick-Change Filter Cartridges can also be used in PriTel's Tunable Filter Module. These external filter modules provide variable center wavelength at a bandwidth fixed by the particular Quick-Change Filter cartridge. With an insertion loss < 0.6 dB and no alignment required, the fiber-pigtailed Tunable Filter Module combines high performance with flexibility and ease of use. The Tunable Filter Module has been used with high satisfaction in scanning supercontinuum pulses.
Embedded microprocessor control
PriTel has engineered the UOC Series for maximum stability and performance. An embedded microprocessor and phase-locked loop (PLL) technology, along with mounting the fiber laser inside a constant- temperature chamber, provide precise control of laser cavity length. Efficient integration of key optical components into subassemblies results in lower power consumption, higher average output power, and enhanced signal-to-noise ratio in the UOC Series.
The display on the front panel shows the status of the UOC's important operating parameters, including the phase-locked loop and the pump laser. Via the embedded microprocessor, these real-time data are available without the need for an external PC. After initial setup, the UOC requires no supervision.
Regenerative mode-locking option
For those researchers who will not be changing the repetition rate, the UOC-R Series uses regenerative mode-locking via an internal, tuned-RF loop to provide the harmonic-mode-locking signal for the laser. This series requires no external RF synthesizer. The UOC-R has an RF-sync output at the frequency of the laser that can be used for triggering and other synchronizations.
