Abstract.

We have measured hyperfine structure in the 5 2P1/2 state of Rb using a frequency-stabilized diode laser, which is locked to one hyperfine transition, and an acousto-optic modulator, whose frequency is locked to the interval of interest. We check for optical-pumping errors by repeating the measurement at different values of pump power in the saturated-absorption spectrometer. We obtain precise values of the hyperfine constant: A=120.645(5) MHz for 85Rb and A=406.119(7) MHz for 87Rb. The values resolve a large discrepancy between two earlier high-accuracy measurements on this state.

  13. The main effect of laser power in resonance spectroscopy is to broaden the line. It is only at very high powers (compared to the saturation intensity) that the lineshape gets distorted due to the creation of “dressed states”. But even under these conditions, the line center remains unaffected Google Scholar
