We performed frequency non-degenerate pump-probe experiments in several direct-gap semiconductors using femtosecond and picosecond pulses. Tuning the long wavelength photons in the IR region, we observed a 125-fold enhancement of the two-photon absorption coefficient. © 2010 Optical Society of America
