Paper Abstract

In our work we investigate the dependence of the CPT canyon width and depth on the radiation fields intensities fields intensities and detunings, the magnetic fields strength and the relaxation constants. We solve the problem of population dynamics for the system of 6P½ 6P3/2 and 7S½ levels of tallium, interacting with two linear polarized monochromatic laser fields and magnetic field, which is perpendicular to the laser propagation direction. Chosen configuration of E- and H-vectors permit us to separate three-level (Lambda) -type system of magnetic sublevels which is uncoupled by radiation fields with the other sublevels. The full set of density matrix equations is solved by a computer. We find the parameters values for which the canyon width is minimal and the depth is maximal. We show that the magnetic field breaks the conditions of equality of laser fields frequencies detunings for CPT. We observe the decreasing of canyon width and depth with increasing of the magnetic field.
