CARIBOU-100: Real-Time Dual-Comb Spectroscopy Averaging System

💥Coming in 2025 Q1!💥

Designed specifically for dual-comb spectroscopy, the CARIBOU-100 system will enable real-time acquisition and processing of interferograms at rates exceeding 100 MS/s. Leveraging a proven correction algorithm, it will efficiently handle delay and phase jitter, providing co-added, high-quality interferograms through a Gigabit interface to a control computer.

The system will also include two CLBs (Comb Lock Boxes), to run servo loops and stream the phase information digitally to the correction algorithm.

The intuitive user interface will offer detailed diagnostics, allowing users to monitor signal-to-noise ratios and jitter levels both before and after correction.

FNC-100 : Fiber Noise Canceller

The FNC is a digital controller intended for applications requiring remote frequency stabilized light sources. In a typical application, a frequency-stable laser will be in building A and sent out to building B over a long optical fiber. The FNC, along with minimal electro-optic components, can be installed at site A to cancel any delay fluctuations arising from the long optical fiber. Features:

• Four independent channels
• Clock input and management
• Trigger input and output signals

CLB : Comb Lock Box

The CLB is a compact, all-in-one, digital phase-lock system for optical frequency combs. It was designed to work with state-of-the art optical clocks. Features:

• Remote control interface through ethernet
• 2 input channels with full phase unwrapping
• Ultra-fast digital PID servo loops
• Clock input and management
• 0-30V output (to control a fast piezo-electric transducer)
• 0-100V output (to control a slow piezo-electric transducer)
• 0-2V output (to adjust the pump laser current)
• Extra digitals IOs
