N2 - A new method of atomic sub-Doppler spectroscopy was developed. The key feature is that the new method uses dual-frequency laser beams in two different optical scheme: with linearly polarized counterpropagating beams with a mutual angle between the polarizations equal to 90 and 45 degrees,, respectively. Due to the CPT effect, a resonance of the opposite sign relative to the saturated absorption resonances was observed.
