Velocity Selective Polarization Spectroscopy for Modulation-Free Dispersion Signals at Detuned Frequencies

Figure 4

VSPS as a pumping beam’s frequency. The pumping beam is locked on the crossover peak between and transition for (a) and (d), resonant peak for (b) and (e), and crossover peak between and transition for (c) and (f). Black lines represent theoretical curves based on Nakayama theory and the red lines represent experimental results in (e)-(f).
