Title:
QCL SPECTROSCOPY SYSTEM AND APPLICATIONS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2011/156818
Kind Code:
A3
Abstract:
A spectroscopy system comprising at least two laser modules, each of the laser modules including a laser cavity, a quantum cascade gain chip for amplifying light within the laser cavity, and a tuning element for controlling a wavelength of light generated by the modules. Combining optics are used to combine the light generated by the at least two laser modules into a single beam and a sample detector detects the single beam returning from a sample.
