Gas laser in a magnetic field

Shape of the coherent-population-trapping resonances registered in fluorescence at different experimental geometries

“…The basic set of equations (6) obtained is analogous to the well known equations 15,16 , but the more detailed calculation of the interaction operators allows simplification of description of the interaction with E and B fields at different geometries and parameters of the experiment.…”

The laser in the axial electric field as a tool to search for P-, T-invariance violation

“…where ω is the laser working frequency, corresponding to the resonator own frequency; m, n are some intermediate atomic levels, ε g , ε c , ε n , ε m are the energies of the levels, d j are the components of the operator d of the atom dipole moment (summation on j is implied in (10) and further), H T is the operator of P-T-violating interaction. We assume that c → g is the laser working transition, and g is the ground state.…”

“…This equation may be derived also in a less heuristic way [9][10][11][12][13]. Losses corresponding to the reflectance of the resonator mirrors can be 'smeared out' over the volume of the resonator through the addition of quantity:…”

“…The simplest type of trap is a laser placed in the electric field (figure 3). This system is similar to the laser in the magnetic field considered in 70th [9][10][11][12][13] and recently as a footing of the laser magnetometers [14,15].…”
