14 May 2013 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. |
