摘要： 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 π 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.
