<500 Picosecond Gating Augments Studies of Atmospheric Pressure Plasma Jets
Non-thermal ‘atmospheric pressure plasma jets’ (APPJs) hold great promise for innovative applications in material processing and biomedicine/healthcare because of their ability to generate plasmas that are not confined between electrodes1. Produced using one of several different experimental setups (e.g., a number of jet configurations are based on dielectric barrier discharge, or DBD), fed with pure rare gases (helium, neon, or argon), and excited by pulsed high voltages, all non-thermal APPJs exhibit a unique feature: they are not continuous media but actually consist of ‘plasma bullets’ traveling at high velocity in ambient air1.

Signal and Noise: How NIRvana Infrared Cameras Deliver Powerful Sensitivity
Infrared imaging in the Short-Wave InfraRed (SWIR) region from 1000-1700 nm wavelength, also known as NIR-II, opens doors to powerful and versatile imaging techniques and applications. This is made possible by InGaAs sensors – sensors where the imaging substrate is composed of a mix of indium, gallium and arsenide instead of silicon.
