Abstract :
We report on high-resolution spectroscopy with dye and diode lasers and with three different samples of Ca atoms, in an effusive beam, in a laser cooled beam, and in a magneto-optical trap. The results should allow to improve the Ca, optical frequency standard, recommended by the CIPM, with a relative uncertainty below 10/sup -14/.<>
