Abstract:

Degenerate four-wave mixing DFWM lineshapes are investigated in sodium vapor near the D2 resonance line using nearly Fourier transform limited pulses. At low pump intensities sub-Doppler resolution is obtained. When the Rabi frequency associated with the pump intensity becomes equal to the ground state hyperfine frequency separation of sodium, each component of the double- peaked DFWM spectrum further splits into two components each. Adiabatic following model explains the near-resonant intensity dependence of the DFWM signal but is insufficient to explain the whole structure.
