Wavelength modulation spectroscopy: combined frequency and intensity laser modulation.
A theoretical model of wavelength modulation spectroscopy that uses a laser diode on a Lorentzian absorption line is presented. This theory describes the general case of a current-modulated semiconductor laser, for which a combined intensity and frequency modulation with an arbitrary phase shift occurs. On the basis of this model, the effect of several modulation parameters on the detected sign...
متن کاملApplying Diode Laser Wavelength Modulation Spectroscopy to Detect Oxygen Concentration
Oxygen is not only important which people rely on but also one type of important industrial gas. Considering that there are some disadvantages of traditional methods to measure the oxygen concentration, the tunable diode laser absorption spectroscopy is researched in this paper combined with the phase-lock amplify technique. This method combines the high power, good monochrome, wavelength tuned...
متن کاملField detection of CO and CH4 by NIR 2f modulation laser spectroscopy
A novel compact fiber-coupled NIR system based on a DFB diode laser source is employed as a portable and sensitive gas sensor for trace detection of combustion pollutant molecules. We demonstrate the performance of such an NIR gas sensor by tracing the absorption lines of CO and CH4 using 2f-WMS technique at moderate temperature of T ~ 600°C in the recuperator channel of an industrial furnace...
متن کاملFrequency modulation spectroscopy with a THz quantum-cascade laser.
We report on a terahertz spectrometer for high-resolution molecular spectroscopy based on a quantum-cascade laser. High-frequency modulation (up to 50 MHz) of the laser driving current produces a simultaneous modulation of the frequency and amplitude of the laser output. The modulation generates sidebands, which are symmetrically positioned with respect to the laser carrier frequency. The molec...
متن کاملWavelength modulation spectroscopy of single quantum dots
We demonstrate that external cavity diode lasers with large mode-hop-free tuning ranges ~up to 80 GHz! together with wavelength modulation spectroscopy can be used to study excitonic transitions in semiconductor nanostructures. Such transitions are characterized by homogeneous linewidths typically on the order of a few GHz. Wavelength modulation spectroscopy offers a high signal-to-noise method...
