Abstract :
1.3- mu m and 1.5- mu m distributed-feedback semiconductor lasers have been frequency stabilized to sub-Doppler resonances of the 5P/sub 1/2/ to 6S/sub 1/2/ and the 5P/sub 3/2/ to 4D/sub 3/2,5/2/ transitions of /sup 85,87/Rb atoms, respectively. Using these stabilized lasers, the absolute wavenumbers of the transitions have been measured interferometrically with an accuracy of 2*10/sup -7/.<>
