Tuesday mornings are arguably the best possible time of the week to be reminded of high school science terms we haven’t thought about for too many decades. Or at least for one Tuesday morning in particular, in which we received an email asking about our experience in gas control for interferometry propagation. We’ll save you a Wikipedia search – lasers; they were referring to lasers. This email was from a leading CO2 fabrication laser manufacturer looking for assistance in solving a gas mixture delivery challenge for an upcoming continuous laser marking application.
