An ultrafast introduction to quantum optics
Quantum optics as a concept dates back to either 1900 or 1905, years when groundbreaking work in the realm of quantum mechanics was published by Max Planck and Albert Einstein, respectively. In Planck’s case, he was working on a discrepancy that later became artfully known as the “ultraviolet catastrophe.” Planck’s solution to this problem, in…

What’s a digital lock-in amplifier, and how does it work?
Digital lock-in amplifiers help scientists and engineers make phase-sensitive measurements of incredibly small alternating current (AC) signals, sometimes buried beneath the noise floor (Figure 1). By providing a lock-in amplifier with a reference signal, a researcher can extract phase and amplitude information from a signal of interest in the same frequency region, even in an…

Optimizing an SRS Lock-in Amplifier for stimulated Raman scattering research
Stimulated Raman scattering (SRS) microscopy is a widely used technique for label-free chemical imaging that leverages the coherent Raman scattering process. While the spontaneous Raman effect is a weak scattering process that can take hours of signal integration time for a single field of view, coherent scattering methods like SRS provide a non-destructive, label-free technique.1…
