  • Method and device for separating molecules having different excitation spectra
    Patent number: 7276103
    Abstract: The invention relates to a method for the separation of molecules having different excitation spectra, which form components of a gas. The molecules are excited by laser pulses in a way that the molecules to be separated are transferred into a state of excitation due to multi-absorption of energy quanta from laser pulses, and in which they are extracted from the gas so that they exist in a composition determined by the form of the laser pulses. According to the invention, the laser pulses are formed by an iterative process in which each laser pulse varies in its form depending on the extracted molecules' composition after their absorption of energy quanta.
