Webinars

In this webinar, Claudius shows how to choose the best measurement approach (lock-in amplification vs boxcar averaging) and settings for your optical measurements to minimize the implementation effort, save time, and record high-quality data with the highest signal-to-noise ratio. The focus is 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. In this blog post, Claudius answers the questions asked during the live session; here he covers some crucial aspects related to the topic of his webinar.

In this webinar, Jelena looks into the basic transport characteristics of materials and nanostructures, and discusses how to set up a lock-in amplifier to perform the fastest measurements with the highest signal-to-noise ratio. An exhaustive summary of her answers to the questions asked during the live session is available here.

In this webinar, Kıvanç looks at the best ways to use time- and frequency-domain tools to characterize sensing devices. In particular, he shows how to set up feedback loops for sensor control without the need for time-consuming and expensive application-specific integrated circuitry (ASIC) development. A detailed blog post accompanies this webinar.

This session features a talk by Prof. Brice Gautier (INSA Lyon) and a tutorial by Dr. Romain Stomp (Zurich Instruments).
In this talk, Brice reviews the technical aspects enabling the use of PFM for domain imaging, hysteresis loops and domain engineering in the DFRT mode. He points out the most common artefacts and shows how experimental conditions influence measured properties. Brice also provides examples of ferroelectric domain control by means of an electric field or mechanical stress. Following the talk, Romain's tutorial looks into the DFRT method and feedback optimization.

This session features a talk by Mr. Valentin Aubriet (CEA-LETI Grenoble) and a tutorial by Dr. Mehdi Alem (Zurich Instruments).
In this talk, Valentin presents a setup for heterodyne Kelvin Probe Force Microscopy (h-KPFM) – featuring the HF2LI Lock-in Amplifier – under frequency-modulated and wavelength-dependent illumination. He then shows how to characterize silicon interfaces embedded under different types of oxides. In the tutorial following this talk, Mehdi discusses electrical pump-probe methods with arbitrary waveform generators.
