“…But, for the target in the liquid, we have to analyze the laser-induced dynamic processes of the gas bubble arising in the liquid as well. By this approach (see [14,16,17]), the additional local pressure 12 atm occurs in the system due to laser action with the power 90 W and a beam having the spot size of about 400 µm for our case.…”

A long linear carbon chain (LLCC)/carbyne synthesis is principal in both theoretical and applied physics. In particular, in the controlling of electrophysical properties due to high polarizability. To synthesize an LLCC, one has to rely on the concept of the compensation process of instability for the linear chain (due to the form of globules and bundles) by some external interaction. In this paper we consider the features of laser experiments for solving the problem. Laser-induced LLCC in the colloidal system was obtained by irradiating a Shungite target in liquid and was stabilized by metal complexes. Some possible applications in nanophotonics are discussed in respect of high/hopping electroconductivity.

The main goal of our work is the laser fabrication of nanostructured materials including the nanoand microclusters for control of electrical, optical and other properties of obtained structures. First, we took an opportunity to select nanoparticles in various sizes and weights and also in topology distribution for some materials (carbon, Ni, PbTe, etc). Second, for a deposited extended array of nanoparticles we used a method of laser-induced nanoparticle fabrication in colloid and deposition metal (and/or oxide) nanoparticles from colloidal systems (LDPCS) to obtain the multilayered nanostructures with controlled topology, including the fractal cluster structures (for Ni, Pb Te et al). Electrophysical properties are analyzed for such nanocluster systems as well. A brief analogy of the obtained nanocluster structures with a quantum correlated state evidence is carried out.

“…Under highly nonequilibrium conditions produced by laser irradiation (elevated temperature, mechanical stress, recombination-stimulated diffusion), surface point defects have high mobility. When the defect density exceeds a critical level, the surface layer becomes unstable, and the planar surface geometry gives way to a periodically bent configuration, with accumulations of interstitials and vacancies in hillocks and valleys, respectively (DD surface instability [2,4]). On the sample surface this is accompanied by an increase in the amplitude of the DD structure, formed by a combination of DD gratings.…”

“…This paper has proposed a method for producing semiconductor nanoparticles of lead chalcogenides with an average size of 5-50 nm by means of continuous laser radiation of a moderate intensity near the infrared range (up to 10 6 W cm 2 ). As our papers [2,3] have shown, the application of continuous laser radiation allows initiation of the nanostructuring of a PbTe semiconductor without specific demands on the environmental conditions. Radiation with 1.06 µm wavelength corresponds to a quantum of photon energy which considerably exceeds the width of a prohibited zone of semiconductors being used.…”

We present the results of laser production of semiconductor nanoparticles under continuous laser action in the near-infrared range (up to 10 6 W cm −2 ) on PbTe samples in air and liquid. We also present a method for forming nanoparticles on the surface of thin PbTe films and consider drop deposition for setting PbTe quantum dots on a substrate. Using a simulation model we describe the features of forming a deposited layer in the process of drop evaporation.
