Abstract

Dark States for Rubidium 85 have been obtained in glass cells containing saturated vapors of natural Rubidium at room temperature. The two radiation, which are required to induce the dark states, have been generated by modulating the light emission of a laser diode, tuned at the S-P optical transition. A measurement of the energy difference between the hyperfine states F equals 2 and F equals 3 of 5S_1/2 is performed by an optical way. By using simultaneously two laser diodes, one tuned at the D₁ transition and the other at the D₂, we have generated two different Dark States. Interference between the two dark states prepared on the same place has been studied by changing the phase of the D₁ and D₂ excitations. A new way to modulate laser beam intensity is shown.
