MOGbox

The MOGbox DLC-202 laser diode controller from MOGlabs is the world's first all-in-one controller for driving and frequency locking an external cavity diode laser. Every model includes:

• ultra-low noise diode current source
• temperature controller with Peltier TEC driver
• scan generator
• two high-voltage piezo supplies
• demodulator (lock-in amp)
• differential photodetector
• ac modulation source (250kHz, 500mA, e.g. for Zeeman dither coil)
• servo feedback loop filter circuits
• ergonomic controls, including 4.5 digit display, oscilloscope selectors, etc.
• in-laser protection/connection board with RF input (2.5GHz bandwidth)
• full set of cables
• manual

All this comes in one box, based on a single 10-layer PCB, with an external photodetector and a protection/connection circuit board for the laser head.

We have used design principles developed by audio (hifi) fanatics, combined with expertise from designing complex 24-layer circuitboards for the optical fibre communications industry. Test results are superior to anything else available commercially; for example, linewidths below 70kHz.
