An experimental model of a universal terahertz laser, created at the Moscow Institute of Physics and Technology (MIPT), has undergone a series of tests and is ready for mass production. The device has confirmed stable operation and compliance with requirements for intended use, reliability, and resistance to external influences.
The development solves the key problem of terahertz technology — complex operation and dependence on cryogenic cooling. The new device operates without liquid nitrogen: active elements are cooled by a built-in refrigerator, and the readiness time for start-up has been reduced to 20 minutes.
The compact case 40×40×40 cm weighs 19 kg and generates radiation in the range of 1.5–4.5 THz. The device has passed climatic, transport, and electromagnetic tests and has confirmed resistance to real operating conditions.
Confirmed parameters include a pulse power of 0.1 mW, pulsed and continuous generation modes, and low beam divergence. The solution will open up applications in gas spectroscopy, environmental monitoring, non-destructive testing, medicine, and new generation communication systems.
