Technology
 
The MonoLux-XX Laser System is a general purpose source of coherent infrared radiation that generates tunable laser radiation in midwave infrared (MWIR). The quantum cascade lasers rely on the principle of band structure engineering to generate light in the MWIR portions of the electromagnetic spectrum. The system operates in quasi-continuous wave (QCW) mode (high duty cycle pulsed operation). The output beam is nominally collimated. The system is fully self-contained and requires only standard mains power and external control computer to operate. Control software that allows flexible wavelength control is provided with the system. The system has TTL level gate output synchronized with the laser tuning which provides means for synchronization of user’s data acquisition system with tuning of the laser. The MonoLux-XX is designed to operate in a normal, climate-controlled laboratory environment.

 

Applications:

  • recognition of various chemical species
  • detection of drugs, explosives, etc.
  • vehicles exhaust emissions detection
  • human exhaled breath gases detection
  • smart sensor networks
  • frequency metrology
  • biological tissue imaging
  • spectrochemical imaging of biofluids
The equipment is of interest for the Romania participation to the COST Actions:
