The structure and optical properties of nanodots based on graphene oxide (GO) obtained by ablation laser radiation with different wavelengths were studied. It was shown that after ablation, the average lateral size GO sheets decreases from 820±120 nm to 204± 40 105± 23 for samples prepared at λ gen =355 532 nm, respectively. In this case, a change in intensities 2D G bands observed, which indic...

Nonlinear optical properties of aqueous dispersions single-wall carbon nanohorns (SWCNH) are investigated by a simple and original technique, relating nonlinear transmittance measurements with semi-empirical model fitting allowing to identify the dominant mechanism. The nanofluids shown particularly strong limiting under irradiation nanosecond laser pulses at 355, 532 1064 nm, much stronger tha...

We present temperature measurements made with the RASC Raman lidar. This instrument, which was optimized for tropospheric and stratospheric temperature profiling, allows to the authors' best knowledge temperature measurements by lidar with at date highest accuracy and resolution in this altitude region. The data were measured with the rotational Raman technique with a laser wavelength of 532 nm...
