TeraHertz (THz) radiation lasers are high-powered lasers with extremely short-bursted pulse, it is great for medical imaging because it is generally not as harmful as compared to x-rays. 

Sacher lasertechnik offers a holistic laser diode system that allows the generation of CW THz Generation using the frequency mixing technique. This technique is achieved by pumping through the Frequency Mixing Crystal via 2 superimposed tunable diode lasers. It is almost plus-and-play; it comes with its own THz software systems with automatic wavelength tuning & it can be remotely controlled by via GPIB, RS232 and USB. 

We distribute CW THz Laser (patented) from Sacher Lasertecnik

Excellent tuning behavior

  • coarse and fine tuning modes of the master lasers
  • fine tuning via piezo actuator with a resolution better than 10MHz
  • manual coarse tuning up to 20THz
  • large mode-hop free tuning range of up to 100GHz and more

Narrow linewidth of seed lasers

  • linewidth < 300kHz
  • excellent side mode suppression > 50dB and >35dB after amplifier

Flexible schemes of realization

  • THz system based on tunable Littman / Metcalf master lasers with free beam optics
  • THz system based on tunable DFB master lasers with free beam optics
  • THz system based on fiber coupled tunable DFB master lasers
  • THz system based on Butterfly packaged, fiber coupled tunable DFB master lasers
     

Application
