Sources Sought - Dual Frequency Comb Laser

Requirements / Specification Document 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.

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. Draft -- 1 of 8 -- Requirements / Specification Document 1-6 1-7 1-8 1-9 1-10 1-11 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.
