Opis:: Experimental results are presented about the transformation of the electromagnetically induced absorption resonance into the electromagnetically induced transparency one. The role of the depolarization of the excited state on the $D_2$ line of Cs atoms exposed to different confinements is discussed.

Opis:: We present the observation of coherent population trapping resonances on the second resonance line of potassium: $4s^{2}S_{1//2}$ → $5 p^{2}P_{3//2}$ with wavelength of 404.4 nm. Moreover, a transfer of the coherent population trapping resonance occurs to the excited $4p^{2}P_{1//2}$ and $4p^{2}P_{3//2}$ states of the first resonance line due to cascade transitions. This transfer is evidenced by the observation of narrow resonances at the infrared $4s^{2}S_{1//2}$ → $4p^{2}P_{1//2}$ and $4s^{2}S_{1//2}$ → $4 p^{2}P_{3//2}$ transitions when alkali excitation is performed at the 404.4 nm violet line.

Opis:: Magnetic field and its gradient measurements based on coherent population trapping resonances at the D$\text{}_{1}$ line of $\text{}^{87}$Rb are performed by means of coupling two ground-state Zeeman sublevels belonging to different hyperfine levels to a common excited state. Two coherent laser fields with frequency difference of 6.8 GHz are used. They are produced by direct current modulation of a diode laser. The resonance splitting and broadening caused by the applied magnetic field is measured by scanning the laser modulation frequency around the ground-state hyperfine frequency.

Opis:: We investigated effects of spatially separated laser fields on amplitudes and widths of electromagnetically induced transparency in M-type atomic system. We have shown narrowing of the electromagnetically induced transmission resonance and therefore enhancement of medium non-linearities that can be explained by diffusion-induced Ramsey narrowing. Depending on the polarization of two laser beams, narrow probe Hanle transmission resonance changes its sign in respect of the profile obtained when the pump laser beam is off.
