Abstract :
An important application of diode lasers in the standards community is the development of the next generation of frequency/wavelength references, where semiconductor laser technology will enable higher performance in portable, inexpensive, and reliable systems. At NIST we are working on an all-diode-laser, optical frequency reference based on the /sup 1/S/sub 0/-/sup 3/P/sub 1/ intercombination line in Ca at 657 nm. This transition is one of those recommended for the realization of the meter, and its absolute frequency has been measured with an uncertainty of 450 Hz, the most precise of any visible reference.
