Pulse generators - Import export

Pulsed terahertz generation with leading-edge technology: InGaAs antennas provide about 30 µW power and a bandwidth of 6 THz. The emitter and detector modules, developed by Fraunhofer Heinrich-Hertz Institute (Berlin/Germany), feature a strip-line and a dipole antenna, respectively, and are packaged with a Silicon lens and SM/PM fiber. They make up the core component of TOPTICA’s TeraFlash pro and TeraFlash smart, but are available as individual modules too.

The new FemtoFiber dichro series simultaneously generates two perfectly synchronized laser beams at different wavelengths. This new concept provides a compact and easy-to-use laser system which requires no more than the push of a button for laser operation. TOPTICA’s first laser system based on this novel platform is the FemtoFiber dichro midIR, which uses this new approach to generate a broadband mid-infrared spectrum. The Er-doped fiber laser based system provides broadband laser pulses that are tunable in the range of 5 - 15 μm. The mid-infrared pulses are generated in a difference frequency process (DFG) between a 1.5 μm fundamental source, and a 1.7 - 2 μm supercontinuum source
