TeraCascade 2000: all features you need in a single box

Maximum reliability

The TeraCascade laser uses the most reliable components available on the market. For example the space qualified cryo-cooler is rated for 200.000 hours of MTBF, which is equivalent to more than 23 years of 24/7 operation.


Ready whatever your application is

Versatility is one of the most important aspects. To achieve maximum flexibility in your application, we have designed a custom laser driver based on several years of user feedback. This allows you to develop any kind of applications.

Quality output beam

The beam quality of a laser source is a crucial point, in particular for imaging application. The TeraCascade laser offers a quasi-Gaussian beam profile and a low beam divergence for an optimal imaging capability.

State-of-the-art technology at everyone's reach

At Lytid, our ambition is to put terahertz technology in everybody’s hands. We have therefore designed the TeraCascade laser with an automatic start-up and shutdown procedure and an easy access to all operating parameters on a touchscreen.
