TERA-Sed Emitters

The Laser Quantum Tera-SED is a device emitting intense terahertz (THz) radiation after excitation with a femtosecond (fs) laser pulse. It converts the light from the optical regime into the THz regime with a conversion efficiency of up to 2 x 10-3.

The impulsive excitation inherently leads to THz pulses covering a broad spectrum in the frequency regime. The spectrum covers almost two decades from about 100GHz up to 7THz with an intensity peak at 1THz. In this frequency range the electric field of the light is directly measurable in amplitude and phase which is important for a large variety of scientific and technological applications.
