The Vapour Cell Lock makes it easy to lock any laser to an atomic transition using saturation spectroscopy. The fully integrated, fibre- coupled package is simple to set up and can be used with a variety of alkali species. An expansion card can be added to the SolsTiS Ice Bloc to provide a complete solution controlled through our Ice Bloc user interface.

OPTIONS
HEATED VAPOUR CELL A heater can be added, with no change in the size of the unit, to increase the vapour pressure inside the reference cell
TUNEABLE OFFSET FREQUENCY Allows lasers to be locked at an offset anywhere from a few MHz up to a few GHz with respect to an atomic transition
