Abstract: The high-resolution spectroscopy of calcium atoms is examined. A strong dipole-allowed 1S 0- 3P 1 transition at 423 rim which allows laser cooling and trapping of calcium and can be assessed by diode lasers. The very narrow 1S 0- 3P 1 intercombination transition at 657 nm (≈10 12) can be used for developing an optical frequency standard. The transitions among the sublevels of the P triplet fall in the far infrared (FIR) and are also suitable for FIR frequency standards. The optical frequency standard can be compact and portable by making use of diode lasers. Free atoms in a beam or trapped cold atoms on a magneto-optical trap can be used.
