摘要： A multifunctional laser device configured to be applicable as such in each of: multiple photon processes, nano structuring processes, optical coherence tomography, Terahertz (THZ) spectroscopy, THz imaging; or a combination of such processes; and comprising a mode-locked linear (X or Z-folded) fs laser resonator having a repetition rate of at least 300 MHz and 600 MHz at most and, thus, a corresponding short resonator length, said fs laser resonator further being a dispersive mirrors cavity having an average negative GDD (Group Delay Dispersion) in the spectral range of the laser operation, and being arranged to generate laser pulses with a pulse width of less than 30fs, and comprising a pump laser operating at an optical output pump power of less than 2W.

摘要： The invention relates to a device for generating terahertz (THz) radiation comprising a short pulse laser (1) with mode coupling to which a pump beam (3) is supplied, and comprising a semiconductor component equipped with a resonator mirror (M4). This semiconductor component serves to derive the THz radiation based on incident laser pulses. The resonator mirror (M4), preferably a resonator end mirror, is provided with a semiconductor layer (8), which is partially transparent to the laser radiation of the short pulse laser (1), whose absorption edge is lower than the energy of the laser radiation of the short pulse laser (1), and on which the electrodes (9, 10) that can be connected to a bias voltage source are placed in order to generate and radiate the THz radiation in the electric field.
