Dispersion spreading of a femtosecond laser pulse in a mixture dry air – water vapor

27th International Symposium on Atmospheric and Ocean Optics, Atmospheric Physics (2020)

P. A. Babushkin Alexey V. Burnashov Anastasiya N. Iglakova Gennadii G. Matvienko V. K. Oshlakov

The results of measure of the duration of a femtosecond laser pulse propagating in a mixture of dry air and water vapor (atmosphere) on a hundred-meter atmospheric track have been presented. Measurements have been made for a spectrally limited pulse and a pulse with initial frequency-phase modulation. A model for calculating the humidity and refractive index of a multicomponent medium for estimating the dispersion spread of an ultrashort pulse in the atmosphere has been discussed.

Experimental study of the characteristics of the propagation of femtosecond radiation: results of the dispersion spreading

Alexey V. Burnashov P. A. Babushkin Viktor K. Oshlakov Anastasiia N. Iglakova

A series of laboratory and full-scale experiments on the propagation of high-power terawatt radiation on the basis of a femtosecond stand of the IAO SB RAS have been carried out. The problem of the spreading of femtosecond pulses in air is considered. The results of the investigation of dispersion spreading of pulses of femtosecond duration are presented.

Measurement of the duration of a femtosecond laser pulse during propagation in the atmosphere

P. A. Babushkin Alexey V. Burnashov Anastasiya N. Iglakova Gennadii G. Matvienko Viktor K. Oshlakov

The problem of the propagation of a femtosecond laser radiation in the atmosphere remains relevant in the application to the problems of remote sensing. When radiation propagates in a multi-component dispersive medium, for example, atmosphere, two important facts are occurred. The first is the transformation of the spectral and spatial characteristics of the radiation. The second is the dispersion modification of the duration. The results of experiments to take into account the dispersion effect of a multi-component medium (atmospheric air) on the duration of a femtosecond wave packet propagating in the atmosphere are discussed.

Application of the using terawatt lidar system of the IAO SB RAS in the case of the remote sensing

23rd International Symposium on Atmospheric and Ocean Optics: Atmospheric Physics (2017)

Alexey V. Burnashov Viktor K. Oshlakov Anastasiya V. Iglakova P. A. Babushkin

A brief description of the unique femtosecond lidar is presented. A number of experiments were conducted on inclined remote sensing of the atmosphere above Akademgorodok, Tomsk (56 ° N, 85 ° E) via this lidar. Questions on the features of the propagation of femtosecond laser radiation, for example filamentation, generation of conic emission of a supercontinuum (SC) are considered. The most important characteristics of the femtosecond lidar system are determined with reference to the problem of remote sensing of the atmosphere, in particular, low cloud cover. The study has a pronounced practical additivity to the use of a femtosecond lidar system in remote sensing problems.

Research of impact of the dispersion effect of the atmosphere on the duration of the femtosecond laser pulse

27th International Symposium on Atmospheric and Ocean Optics, Atmospheric Physics (2019)

P. A. Babushkin Alexey V. Burnashov Anastasiya A. Iglakova G. G. Matvienko Viktor K. Oshlakov

One of the actual problems of the multi-frequency laser remote sensing is the using of the self-action phenomena of pulsed femtosecond laser radiation. When femtosecond laser radiation propagates in the atmosphere, both the transformation of the spectral and spatial characteristics of the radiation dispersion and the pulse duration occurs. The effect of atmospheric air dispersion on the duration of a femtosecond pulse propagating in the atmosphere is discussed via the results of experiments. The fact of compensating of the dispersion spreading of the pulse duration in air by its temporary "compression" under the influence of a change in the phase modulation index in an optically active impurity is not excluded.

Mueller matrix for preferably oriented ice crystal particles of cirrus clouds

Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE (2011)

Alexey V. Burnashov

Mueller matrices for ice crystals horizontally and preferably oriented in horizontal plane are calculated with a code ("facet-tracing") based on the geometric optics. For the case of preferably oriented ice crystals particles uniform and normal distributions of flutter with maximum dimension of 5° are analyzed. The main physical regularities inherent to the scattering matrices are discussed. Degree of polarization of the scattered light is shown to be a qualitative criterion of number of photon trajectories that contribute effectively to the scattered light. The inverse scattering problem of retrieving aspect ratios of the horizontally/preferably oriented hexagonal ice plates from polarization of the scattered light in the bistatic sounding scheme has been proposed and discussed.
