Abstract: A device and method for producing a third harmonic signal from an optical pulse of wavelength k. In the device and method, an optical pulse at a wavelength k is incident on a material including at least one molecule having a formula D-U-A, where D is an electron donor group, A is an electron acceptor group, and ? is a conjugated structure having it bonds that connect D to A. The molecule exhibits a strong absorption band centered at a wavelengthko and a weakly absorbing region centered at a wavelength k, which is less than Xo. A wavelength k/2 has a value of about Xo, and a wavelength k/3 has a value of about X1. A third harmonic signal at k/3 is generated. From a measured third harmonic signal as a function of a time delay for separate optical pulses entering the material, at least one of a pulse width and a pulse shape of the optical pulse can be extracted. From a spectrally resolved third harmonic signal, a phase of the optical pulse can be extracted.

Abstract: Compositions capable of simultaneous two-photon absorption and higher order absorptivities are disclosed. Many of these compositions are compounds satisfying the formulae d-A—D, A—A—A, D—A—D and A—D—A, wherein D is an electron donor group, A is an electron acceptor group and A comprises a bridge of B-conjugated bonds connecting the electron donor groups and electron acceptor groups. In A—D—A and D—A—D compounds, the B bridge is substituted with electron donor groups and electron acceptor groups. Also disclosed are methods that generate an electronically excited state of a compound, including those satisfying one of these formulae. The electronically excited state is achieved in a method that includes irradiating the compound with light. Then, the compound is converted to a multi-photon electronically excited state upon simultaneous absorption of at least two photons of light.
