Quantum cascade laser-based wavelength modulation spectroscopy

Not Accessible

Your library or personal account may give you access


A new calibration-free 1f and 2f wavelength modulation spectroscopy technique is demonstrated on a quantum cascade laser to measure ambient CO and CO2. The method is robust, highly sensitive and usable in congested spectral regions.
