“…In this context, the development of new in situ LiDAR systems can contribute to the design of future space missions by providing useful data for pre launching tests. In this issue a LiDAR system, designed for detection and investigation of aerosol-gas formations in the atmosphere, as presented by Gritsuta et al (2018), is a contribution to a better definition of information needed for atmospheric corrections of ocean colour data in coastal regions.…”

“…In particular, fluorescence and FIBS LiDARs are created worldwide, which demonstrates their capability for determining the impurities in the atmosphere based on databases of fluorescence and emission species spectroscopy [2,3]. Nowadays, LiDARs are capable of measuring gas aerosol formation in the atmosphere at sufficiently long ranges (up to 3 km [4]) or extracting forest canopies from the urban landscape [5].…”

Femtosecond laser-induced fluorescence (FLIF) and femtosecond laser-induced optical breakdown spectroscopy (FIBS) are important tools for remote diagnostics of atmospheric aerosols using LiDAR (Light Identification Detection and Ranging) technology. They are based on light emission excitation in disperse media via multiphoton nonlinear processes in aerosol particles induced by high-power optical pulses. To date, the main challenge restraining the large-scale application of FLIF and FIBS in atmospheric studies is the lack of a valued theory of the stimulated light emission in liquid microparticles with a sufficiently broad range of sizes. In this paper, we fill this gap and present a theoretical model of dye water droplet emission under high intensity laser exposure that adequately simulates the processes of multiphoton excited fluorescence and optical breakdown plasma emission in microparticles and gives quantitative estimates of the angular and power characteristics of nonlinear emission. The model is based on the numerical solution to the inhomogeneous Helmholtz equations for stimulating (primary) and nonlinear (secondary) waves provided by the random nature of molecule emission in particles. We show that droplet fluorescence stimulated by multiphoton absorption generally becomes more intense with increasing particle size. Moreover, far-field plasma emission from liquid particles demonstrates a larger angular diversity when changing the droplet radius in comparison with multiphoton excited fluorescence, which is mainly due to the excitation of the internal optical field resonances in spherical particles.
