1060nm Ultrafast Optical Clocks

Ultrafast Optical Clock

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 at 1060 nm. The UOC can be used as a source for Solitons, RZ Optical Pulses and Optical Clocks. This high performance unit provides short pulses for telecom research and low jitter pulses for a variety of research applications.

One research application using this laser is reported in the OFC/NFOEC 2006 Post Deadline Paper:
"10 GHz 0.5 ps Pulse Generation in 1000 nm Band in PCF for High Speed Optical Communication" by K. Kurokawa, K. Tajima, and K. Nakajima of NTT Corporation.

Unique Features Repetition rates from 0.5 to 20 GHz Variable*
Wavelengths from 1040 to 1080 nm Variable*
Pulsewidths from 2 to 25 ps Variable*
Embedded microprocessor control *

Why choose a our 1060nm fiber laser? Excellent contrast ratio (>40 dB)
Low timing jitter (typically <100 fs)
Chirp-free soliton pulses
Tunable Wavelength
High output power (10 mW at 10 GHz)
High pulse-repetition rates (upto 40 GHz)

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.

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.
