“…Glavez et al used the femtosecond supercontinuum generated in rare gas before transmitting into the atmosphere to perform multi-wavelength Lidar and characterize aerosols [150]. Since the continuum has the same polarization as the incident laser pulse, depolarization measurements are also possible.…”

Physics and applications of atmospheric nonlinear optics and filamentation

Abstract:We review the properties and applications of ultrashort laser pulses in the atmosphere, with a particular focus on filamentation. Filamentation is a non-linear propagation regime specific of ultrashort and ultraintense laser pulses in the atmosphere. Typical applications include remote sensing of atmospheric gases and aerosols, lightning control, laserinduced spectroscopy, coherent anti-stokes Raman scattering, and the generation of sub-THz radiation.

“…1,2 The same approach was also used to characterize aerosols along a path by monitoring the intensity variations of the scattering phase function for a range of backscattering angles. 3,4 Earlier approaches, often referred to as differential optical absorption spectroscopy (DOAS), employed lamps or lasers to make horizontal path absorption measurements. [5][6][7][8][9] Tomographic routines analogous to those developed through the work of Hashmonay and Yost 10 and Price 11 can then be employed to retrieve a range-resolved component for long-path absorption measurements.…”

Abstract. The concentration of atmospheric oxygen is measured over a 540-m path using supercontinuum absorption spectroscopy. The absorption data compared favorably with MODTRAN™ 5 simulations of the spectra after adjusting for the differences of index of refraction of air and matching the instrument spectral resolution, as described by the effective slit width. Good agreement with the expected atmospheric oxygen concentration is obtained using a previously developed multiwavelength maximum likelihood estimation inversion algorithm. This study demonstrates the use of the SAS technique for measuring concentrations of chemical species with fine absorption structure on long-atmospheric paths. © The Authors.Published by SPIE under a Creative Commons Attribution 3.0 Unported License.

“…This property makes it particularly suitable for spectroscopic applications. It has been proposed as a collimated light source to measure simultaneously the absorptions of all the species present along the laser path beyond the filamentation region, an approach known as ''white-light DIAL'' (Differential Absorption Lidar) or ''multi-DIAL'' [9,[25][26][27][28]. Multi-DIAL can be seen as a generalization of standard DIAL, in which a wavelength pair is matched to the spectrum of the predetermined species to detect: one wavelength absorbed by the molecule to detect and the other used as reference.…”

“…In order to assess the potential of the multi-DIAL technique, the evolution of the white-light Lidar signal intensity with laser power is a key information. Most of the previous results were obtained at powers on the TW level [25][26][27][28]. However, laser technology allows now increasing the power level by orders of magnitude.…”

White-light femtosecond Lidar at 100 TW power level

et al. 2013

View full text Add to dashboard Cite

We characterized the white-light supercontinuum emission by a sub-petawatt laser system in the atmosphere via light detection and ranging measurements. As much as 1 J of supercontinuum is generated in the atmosphere, corresponding to a conversion efficiency of 30 %. This generation occurs at altitudes below 100 m. The high initial beam intensity results in the saturation of the number of self-guided filaments. Therefore, the “photon bath” surrounding the filaments strongly contributes to the white-light generation. These finding is well reproduced by numerical simulations based on the experimental parameters
