Abstract
A narrowband R-type resonance is formed in a Λ-system, on the D1 line of Rb atomic vapor using two continuous diode lasers with λ=795 nm. A 8mm- long cell filled with the Rb vapor and 20 Torr neon gas has been used. We have shown that use of an additional (3rd) laser which is resonant with the Rb D2 line (λ=780 nm) makes it possible to control the amplitude and sign of the R -type resonance, i.e. to convert a resonance which demonstrates increase in absorption into one which demonstrates reduction in absorption. The good signal/noise ratio of the observed resonance allows us to follow its behavior in an applied magnetic field from several gauss to several hundred gauss. A description in terms of double-Λ systems allows us to explain the experimental results in a simple manner.
