A next generation laser driver and temperation controller — •Patrick Baus, Thomas Sattelmaier, and Gerhard Birkl — Institut für Angewandte Physik, TU Darmstadt, Schlossgartenstraße 7, 64289 Darmstadt, Germany
We present a fully open source hardware solution for the next generation of diode lasers. Our solution provides superior performance in comparison to typical commercial solutions in the field, while being more economical and versatile due to its open source platform. Our laser current driver offers full digital control, sub-ppm drift and the lowest noise in class. Additional features are a high compliance voltage of more than 10 V to drive modern and exotic laser diodes and a modulation bandwidth with linear response of more than 1 MHz.
Our temperature controller features best in class noise of <5 µKRMS and stability of <100 µK (@ 25 ∘C) over several weeks limited only by ambient humidity. Our system offers two channels with independant control and up to 60 W.
For both devices, we intend to make the hardware and software publicly available under an open source license to allow full customization.
