Abstract:
1. A device for generating terahertz (THz) radiation having a short pulse laser with mode locking to which a pump beam is supplied, and a semiconductor component including a resonator-mirror, which semiconductor component simultaneously is designed for generating the THz radiation on the basis of impacting laser pulses, characterized in that the resonator mirror (M 4 ) is provided with a semiconductor layer ( 8 ) which is partially permeable for the laser radiation of the short pulse laser ( 1 ), the absorption edge of the semiconductor layer being below the energy of the laser radiation of the short pulse laser ( 1 ), and electrodes ( 9 , 10 ) connectable to a bias voltage source being mounted thereon so as to generate the THz radiation in the electric field and radiate it.
