TIME FOURIER SUPERHIGH RESOLUTION SPECTROSCOPY

Fundamental principles of time Fourier superhigh-resolution laser spec troscopy on the basis of the pulse optical fields are reported. Experi mental results on the obtainment of high stable ultrashort optical pul ses using a self-mode-locked laser and phase synchronization of pulse repetition frequency by means of an external highly stable rf generato r are described. The possibility of the application of the new method of precision spectroscopy for absolute frequency measurements is consi dered. The concrete schemes of absolute frequency measurements in the IR, visible, and UV spectral regions are discussed.
