In collaboration with Professor Qing Hu'sresearch group from the Massachusetts Institute of Technology (MIT) in the USA, our research team recently demonstrated terahertz quantum cascade lasers (THz QCLs) that established a world record for high-temperature operation. Moreover, the portable size of this QCL device now makes the generation of high-power terahertz radiation outside of a laboratory environment possible.

This work is reported in Nature Photonics.

"Many authorities in the field didn't believe these devices could work outside a laboratory environment or anywhere close to room temperature," said Professor Zbig Wasilewski and as commented by Professor Qing Hu from MIT,

With a high operating temperature, we can finally put this in a compact portable system and take this breakthrough technology out of the laboratory.
