LongWave Photonics was founded by Prof. Qing Hu (MIT) and Dr. Alan Lee in 2010 with the goal of making THz Quantum Cascade Lasers (QCLs) available to industrial, academic and government researchers without the need for specialized cryogenic or vacuum systems. LongWave Photonics has developed easy to use systems and provides "turn-key" solutions to its users. LongWave Photonics' QCL systems deliver milliwatt average power levels over a range frequencies from 1.9 to 5 THz in compact, cryogen free packages. These high average power levels allow real-time imaging, spectroscopy and tomography for research and industrial applications.
