Digital Diode Laser Controller (dDLC)

The MOGLabs Digital Diode Laser Controller is our next-generation controller for precision tunable lasers. It combines the ergonomic ease-of-use of our classic analogue DLC, with the flexibility and performance of a fully digital system.

It offers a combination of impressive performance and ease-of-use, using the front panel with high resolution display, or our comprehensive Windows app, or your own code using the simple text-based command language that MOGLabs is famous for.

The dDLC is designed for the ultimate applications in quantum computing, quantum sensing, time and frequency standards, gas sensing, and spectroscopy.

The full list of features for the dDLC include:

• Fully digital with high-speed FPGA signal processing.
• Bullet-proof laser operation: can reset the microcontrollers without affecting laser lock.
• Current, temperature and piezo controllers with lowest commercially available noise and drift.
• Internal spectrum analysis with high dynamic range and bandwidth.
• Complex frequency feedback locking via FPGA signal processing. Side of fringe, top of fringe locking and auto-relocking (in development).
• Auto-optimise of feedback servos using live noise spectral analysis.
• Signal display oscilloscope functionality on device, with specific knobs to control key functions (diode current, laser frequency and span, input signal offset, slow and fast gain).
• Completely self-contained: tune and lock to atomic resonance without computer connection.
• Full device control using on-screen menu.
• Sophisticated and intuitive GUI for remote operation via TCP/IP or USB.
• Easy to use text-based control API; no DLL or drivers needed. Python, LabVIEW, matlab bindings and examples provided.
• Online user manuals, software updates, app notes; no login details required.
