Abstract :
The improvement of the short term stabilization scheme of an Ar+ laser for the realization of an optical frequency standard at 501.7 nm is described. The laser frequency is locked to a Fabry-Perot resonator mode for the very short term stabilisation and to a hyperfine transition detected in iodine for frequency correction in the range 1-100 Hz. A device for the amplitude noise rejection is developed to increase the signal to noise ratio of the detected signal. The new stabilization system leads to frequency stability at the 10-13 level for 1 s integration.
