Technical specification for Optical frequency comb with visible output purchase for NIST-ADI (6/19)

One (1) EACH optical frequency comb with the following specifications:

· Er:doped fiber polarization maintaining oscillator engineered for metrology applications

· Includes laser head and control unit

· Repetition rate 250 MHz

· Center wavelength 1560 nm +/20 nm

· Spectral bandwidth of output >25 nm

· Six PM (polarization maintaining) fiber coupled output ports, linearly polarized; each port with average output power >12 mW, LC/APC connectors

· All six outputs can be turned into high power ports by adding EDFA amplifiers.

· Monitor port, FC/APC connector

· Integrated stepper motor for tuning of cavity length by >4 MHz

· Piezo actuator for repetition rate synchronization

· Control of CEO frequency through intracavity actuator by >250 MHz and pump power modulation for fine control and stabilization

· Actuators for high bandwidth intracavity feedback for the repetition rate and CEO frequency with typical control bandwidth of 1 MHz

· RF input (4) for fast/slow stabilization of repetition rate and fCEO

· fCEO stabilization optics including oscillator amplifier, non-linear fiber for spectral broadening, f-2f interferometer, fCEO phase detection and phase lock loop for stabilization

· Optics for visible spectrum extension including oscillator amplifier, frequency double and non-linear fiber for spectral broadening at ~800 nm
