Fiber Noise Cancelation System: FNCS-1000-1

What good is stable light if you can’t share it? Transfer your stable light to the next room or the next building and stay on frequency

Our one-of-a-kind Fiber Noise Cancelation System solves the problem of sending frequency stabilized light down a noisy optical fiber by providing accurate phase noise cancelation at the outset to maintain stable, narrow linewidths. We’ve combined the best techniques available into a single unit with a dramatically reduced footprint that works with any stabilized laser system. Our touch-screen interface controls an all-digital architecture to quash unwanted phase noise at the push of a button. 

Extend the reach of your stabilized light
