Power instabilities and high noise levels are common, when there is a tendency for optical feedback in the set-up (e.g. back reflections from fiber end-facets or from highly reflective samples). The Feedback Induced Noise Eraser (FINE) of TOPTICA's iBeam smart lasers eliminates this problem. A simple push of a button makes these lasers ultra-stable against optical feedback. Customers save time and costs, by making re-alignment and optical isolators unnecessary.
