Ultrastable frequency reference at 1.56 μm using a CO molecular overtone transition with the noise immune cavity-enhanced optical heterodyne molecular spectroscopy method

Shailendar Saraf, Paul Berceau, Alberto Stochino +2

We report on an ultrastable molecular clock based on the interrogation of the 3ν rotational-vibrational combination band at 1563nm of carbon monoxide 12C16O. The laser stabilizatio…
