TITLE: Dual Frequency Comb Laser

Requesting Laboratory / Division / Group:

Communications Technology Laboratory 672 Division

Waveform Metrology

General Statement of Need:

A dual optical frequency comb system is required for electro-optic sampling and characterization of radio-frequency and sub-terahertz electrical waveforms with measurement capability extending toward 1 THz. The system shall operate near 1550 nm to maximize compatibility with commercially available ultrafast electro-optic sampling components. It must provide two mutually coherent ultrafast pulse trains with stable repetition-rate offset control suitable for asynchronous dual-comb waveform reconstruction, including simultaneous amplitude and phase recovery through time-domain sampling and Fourier transformation. The system should provide sub-picosecond pulses, low timing jitter, clean spectral and temporal characteristics, RF synchronization outputs derived from internal photodiodes, optical monitor outputs, and both fast and coarse repetition-rate tuning actuators to support phase locking and long-term stabilization. The architecture shall support low-noise dual-comb EOS measurements with high temporal fidelity, broadband electro-optic interaction, and stable operation in a controlled laboratory environment using standard 115 V power.

250 MHz repetition-rate femtosecond fiber laser with factory-set repetition-rate matching between two systems to within <1 kHz at nominal piezo voltage.

Center wavelength tunable within 1545–1570 nm with target operation near 1555 nm for compatibility with 1550 nm EO sampling and fiber infrastructure.

Fiber-coupled output power specified between 30–50 mW with PM FC/APC output and PER >20 dB.

Frequency-comb-optimized configuration with guaranteed free-running timing jitter below 20 fs over 1 kHz–10 MHz integration bandwidth.

Integrated fast/fine piezo actuator with >20 kHz tuning bandwidth and resonance frequency typically >100 kHz for rapid repetition-rate stabilization.

Independent coarse piezo actuator providing >6 kHz long-term repetition-rate tuning range for extended frequency locking and environmental drift compensation.

Internal RF photodiode output with AC-coupled SMA connector generating clock output at the laser repetition frequency.

Dedicated optical monitor output port (>2 mW) aligned to the slow axis of PM fiber for synchronization and diagnostic monitoring.

Low-noise ALM05 filtered power supply with <50 µVRMS noise over 1 Hz–1 MHz and <1 µV/√Hz noise density above 10 Hz to minimize electrical noise coupling into timing stability.

Hermetically sealed passively air-cooled compact laser enclosure (250 × 60 × 260 mm³) optimized for stable long-term laboratory operation without water cooling.

The equipment must be new (not refurbished or reconditioned) and covered by the original manufacturer’s full warranty with service provided by that manufacturer’s U.S.-based service organization.
