The initiation of plasma using grapes in a commercial microwave oven is a well-known parlour trick. All prior demonstrated approaches use cut grape hemispheres connected with a “skin bridge” the common explanation for the mechanism of ignition involves conduction in the bridge or in the grapes themselves. We have studied this phenomenon in detail and present new experimental observations, scientific...
Carotenoids are highly conjugated natural polyenic compounds with notoriously large optical nonlinearities. The commercial importance of carotenoids such as β-carotene and astaxanthin currently exceeds $500M, as these compounds are used as dyes, natural supplements, cosmetics, and food additives. Furthermore, biologically, carotenoids are used for many purposes, including as optically important components...
We utilize second-harmonic- and sum-frequency-generation at the objective focus to optimize spectral resolution in a single-fs-laser-source CARS microscope. Chirp-matching provides spectral focusing with a <40 cm−1 resolution between 1200 cm−1–3800 cm−1.
We generate a highly-controlled, optically-dense, and repeatable Rb vapor inside of a hollow-core photonic bandgap fiber using light-induced atomic desorption. Here we present its generation dynamics and use for nonlinear quantum optical applications.
