1.3-µm and a 1.5-μm distributed-feedback semiconductor lasers have been frequency stabilized to sub-Doppler resonances of the 5P1/2→ 6S1/2and the 5P3/2→4D3/2, 5/2transitions of 85, 87Rb atoms, respectively. Using these stabilized lasers, the absolute wavenumbers of the transitions have been measured interferometrically with an accuracy of 2 × 10-7.
