Controller for diode lasers (DLC)

The MOGbox DLC laser diode controller is an all-in-one controller for driving and mode coupling MOGlabs lasers or other ECDLs.
Each model includes:

• Ultra-low-noise diode power source, < 100 pA/rtHz, DC up to 1 MHz
• Temperature controller with Peltier-TEC driver
• Scanning generator
• Two high-voltage piezo drivers
• Differential low-noise photodetector, 700 kHz bandwidth
• Lock-in amplifier
• AC modulation source (250 kHz, 50 mA, e.g. for Zeeman dither coil)
• Filter circuits for servo feedback loop
• Ergonomic interface, including 4.5 digits display, oscilloscope selection switch
• Laser-internal connection and protection board with high modulation bandwidth
• Complete cable set and 120-page detailed user manual

After 20 years of experience, MOGlabs has developed a successor to the DLC, the dDLC (digital Diode Laser Controller). This has the same features as the DLC, but has significantly more options:

• Feedback servos for mode coupling
• Fast FPGA signal processing
• Complete operation via the user-friendly display on the device or the GUI on the computer via TCP/IP or USB connection
• Oszilloskop-Modus, dafür extra ausgerichtete Bedienung zur Einstellung von Diodenstrom, Frequenz, Signal-Offsets oder Gain, etc.
• Coupling to an atomic resonance is possible with the dDLC itself, without additional devices for laser control

Features

• Power source with extremely low noise
• Double feedback servos
• Modulator driver
• Temperature controller
• Lock-in amplifier
• Piezo driver
• Sweep-Rampen-Generator

Applications

MOGlabs’ drivers are primarily used with their external cavity lasers, but together with other similar lasers they can also be used in the following fields:

• Laser cooling and trapping
• Bose-Einstein condensation
• Quantum computer for trapped ions
• Quantum optics
• Electromagnetic transparency and slow light
• Time and frequency standards
• Laser spectroscopy
