Multiferroic hexagonal manganites ReMnO3studied by optics are reviewed. Their electronic structures were revealed by static linear and nonlinear spectra. Two transitions located at~1.7 eV and~2.3 eV have been observed and attributed to the interband transitions from the lower-lying Mn3+dxy/dx2-y2anddxz/dyzstates to the Mn3+d3z2-r2state, respectively. These so-called d-d transitions exhibit a blueshift as decreasing temperatures and an extra blueshift nearTN. This dramatic change indicates that the magnetic ordering seriously influences the electronic structure. On the other hand, the ultrafast optical pump-probe spectroscopy has provided the important information on spin-charge coupling and spin-lattice coupling. Because of the strongly correlation between electronic structure and magnetic ordering, the amplitude of the initial rising component inΔR/Rshows striking changes at the vicinity ofTN. Moreover, the coherent optical and acoustic phonons were observed on optical pump-probe spectroscopy. Both the amplitude and dephasing time of coherent phonons also exhibit significant changes atTN, which provide the evidence for spin-lattice interaction in these intriguing materials.

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.
