New technologies based on smaller and ever-more powerful devices often require precise measurements of tiny signals that are buried in noise.

In this tutorial, we learned how to use lock-in amplifiers and optimize measurement parameters to get the best signal-to-noise ratio. We discussed three common use cases: optics and photonics experiments, material characterization, and resonator characterization. Finally, we looked at more advanced techniques, such as double modulation and multi-frequency measurements.

In this webinar, Claudius shows how specific settings on lock-in amplifiers and boxcar averagers impact the results of a measurement in optical experiments by looking at the filter function, the filter order and the time constant. He then discusses the relevance of typical properties of electronic measurement devices for optical experiments such as the instrument's dynamic range, measurement bandwidth and signal input noise. Claudius answers the questions asked during the live session in this blog post.

In this webinar, Claudius and Romain are joined by Prof. Markus Raschke (University of Colorado Boulder) and his student Mr. Samuel Johnson to present the growing field of tip-enhanced scanning probe microscopy and its application to precision spectroscopy, ultrafast-nano-imaging and, in the strong coupling limit, cavity quantum electrodynamics. In particular, Claudius shows how to maximize the signal and image information content with advanced measurement instrumentation. Claudius, Markus and Samuel answer many of the questions asked during the live event here.

In this webinar, Claudius focusses on four prototypical techniques in optics and photonics: tunable diode laser absorption spectroscopy (TDLAS), pump-probe spectroscopy, stimulated Raman scattering (SRS), and carrier-envelope offset (CEO) stabilization. He looks into how to choose the most suitable measurement scheme for your experiment, e.g. a lock-in amplifier or a boxcar averager, and discusses how to save precious measurement time and record high-quality data with the highest signal-to-noise ratio. Claudius answers the questions asked during the live session here; he covers some crucial aspects related to the topic of his webinar in this blog post.
