Interference effects in time-delayed degenerate four-wave mixing with broadband noisy light
Valery P. Kozich, Leonardo de S. Menezes, Cid Bartolomeu de Araujo
Femtosecond beats in time-delayed forward degenerate four-wave mixing (DFWM) with incoherent light in liquid and solid materials have been observed, and their origin is discussed. It is shown that the oscillations are due to the interference between pure DFWM signal and Rayleigh scattering from the excitation beams. It is also shown that, if this effect is not taken into account, incorrect conclusions can be reached.
