In March 2011, Nanosurf and Zurich Instruments announced a cooperation to establish the HF2PLL as official upgrade path for Nanosurf’s EasyPLL. This post shows how to connect Nanosurf’s Manual Controller to the Zurich Instruments HF2PLL. The Manual Controller combined with [...]

In this post, I demonstrate the capabilities of the HF2LI-MOD upgrade by demodulating 4 FM sidebands simultaneously. With the help of a basic sweep routine programmed in LabVIEW, I measure 5 Bessel functions by direct sideband demodulation of an FM signal. This post might give you an inspiration on how to improve your measurement sensitivity by introducing an advanced demodulation scheme of multiple sidebands.

There is a new application note about pseudoheterodyne detection in nearfield optics. The application has also relevance for laser spectroscopy. Hereafter are a few personal comments about phase sensitive detection in optics, as I participated in the described experiments.
