Patent ID: 7894126

Claim:
A broadband Terahertz radiation generation and detection system comprising: a light source for generating a pump beam and a probe beam each comprising light pulses in the optical range having a pulse duration in the picosecond- or sub-picosecond range, the light source comprising a laser; a first nonlinear optical crystal arranged in a pump beam path, wherein a Terahertz beam is generated upon exposure of the first nonlinear optical crystal with the pump beam; a second nonlinear optical crystal arranged in a probe beam path and in a Terahertz beam path, wherein optical properties of the probe beam are altered when the second nonlinear optical crystal is exposed with the probe beam and the Terahertz beam; a detector for detecting predetermined optical parameters of the probe beam, wherein the light source generates the pump beam with a central frequency ω corresponding to the central frequency of the laser and generates the probe beam with a central frequency 2ω by second harmonic generation with a further nonlinear optical crystal.
