CoSy
Compact module with saturation spectroscopy cells
Three is the charm: Rb, Cs and K, all in one module
CoSy
Compact module with saturation spectroscopy cells
The CoSy system generates both purely Doppler-free and purely Doppler-broadened absorption saturation spectra, which can be fed directly to appropriate stabilization electronics. It can conveniently be used for top-of-fringe stabilization with a modulation technique. The CoSy module helps the customer to save time and space in his experiment. The absorption cell of the Cosy is filled with Rb, Cs and K and one can easily reach a long-term stability of the optical frequency below 1 MHz (corresponding to a relative stability of 10-9) for the considered transitions.
