Patent number: 9983126Abstract: A system and method are disclosed for gas sensing over a wide tunable wavelength range provided by one or more quantum cascade lasers. A laser beam is generated within the wide tunable wavelength range, which is given by the sum of the wavelength ranges from the individual lasers. Gas sensing or detection is achieved by obtaining an infrared absorption spectrum for a sample contained in one or more cells having different path lengths for the laser beam.Type: GrantFiled: February 6, 2016Date of Patent: May 29, 2018Assignee: Block Engineering, LLCInventors: Petros Kotidis, Erik Deutsch, Hongke Ye, Alexander Mazurenko, Anish K.
