@article{2015-seidler, Abstract = {This work reports on a high bandwidth (>0.5 MHz) digital controller for intensity stabilisation. Important properties of the digital hardware are characterised. The noise characteristics of the digital to analogue converter limit the digital controller, making it inferior compared to a state-of-the-art analogue controller in this respect. However, similar bandwidths are achieved with both controllers in PI mode. In addition a proof of concept digital Internal Model Controller is presented showing an increased bandwidth of 2.4 MHz. The results and methods presented in this work may be used to improve intensity control for quantum optics experiments using digital controllers.}, Author = {Seidler, F.}, Journal = {}, Pages = {}, Title = {{Digital high bandwidth feedback controller}}, Volume = {}, Year = {2015} }
