We present the results of nonlinear optical pump-probe experiments on photoactive yellow protein (PYP). We are able to completely bleach the 446 nm absorption peak of PYP by one-photon excitation using a cw argon laser. We calculate the corresponding index change and find it to be similar to that of bacteriorhodopsin. We also determine an upper limit to the two photon absorption cross-section of PYP by looking for bleaching of the 446 nm absorption peak under irradiation by femtosecond pulses at 820–910 nm. No TPA signal is observed.
