SLM Technology as a Tool for Serial Production DOI: 10.22184/1993-7296.FRos.2026.20.4.248.252
Selective laser melting (SLM) technology has become firmly established in the development of new products, no longer being perceived as an innovative experiment. At the current stage of the industry’s development, the key challenge is scaling this experience: additive solutions must become a cost-effective choice for medium-sized industrial enterprises across various sectors. Dmitry Vasiliev, General Director of Laser Systems JSC, Candidate of Technical Sciences, discussed ways to overcome industry conservatism, identify areas of maximum SLM efficiency, and why additive products should become serial standards rather than unique laboratory samples.

Running Hurdles DOI: 10.22184/1993-7296.FRos.2026.20.4.260.265
Additive technologies are actively reclaiming their place in the field of mass production, leaving the well-established experimental niche in engineering laboratories, startups, and R&D. Although additive manufacturing is entering the phase of industrial maturity, discussions about overcoming the barriers to the advancement of additive technologies are ongoing, with the lack of a unified regulatory framework being a major concern. Additive technologies can create unique and complex products, but the absence of standards makes it difficult to certify, control quality, and widely adopt them in critical industries. Nevertheless, the additive technology market is growing both globally and in Russia, as evidenced by various studies.

Application of Neural Networks to Improve the Reliability of Assessing the Capabilities of Television Reconnaissance Equipment DOI: 10.22184/1993-7296.FRos.2026.20.4.284.296
This article proposes a methodological approach to enhancing the timeliness of assessing the capabilities of television reconnaissance systems through the application of up-to-date technologies, including neural networks. A combined methodology is introduced, integrating an algorithmic method developed in the previous stage, based on the object brightness coefficients, background specifications, and critical target sizes, with the modern computer technologies. Particular emphasis is placed on the integration of convolutional neural networks to automate image processing, improve recognition accuracy, and minimize subjective factors.

Focusing Specifications with a Small Pupil Size DOI: 10.22184/1993-7296.FRos.2026.20.4.272.282
The influence of diffraction at a circular aperture is investigated in the analysis of nonparaxial focusing by parabolic and ideal lenses at small pupil sizes. The performance of such focusing elements is illustrated using a nonparaxial diffraction model based on the Rayleigh-Sommerfeld integral. The analytical and numerical results demonstrate that nonparaxial effects and the differences in the behavior of two lenses depend not only on the numerical aperture of the optical element (the ratio of its radius to focal length) but also on the pupil size. When the aperture approaches a “pinhole”, i. e., its radius is only a few wavelengths, the combined effect of the lens and the pupil must be considered.

“Smart Heat”: Inactivation of Pathogenic Microorganisms by Femtosecond Laser Radiation in the Mid-Infrared Range DOI: 10.22184/1993-7296.FRos.2026.20.4.298.310
The food industry and healthcare need to develop new universal and non-resistance-inducing methods of inactivation of pathogenic bacteria that would provide the necessary level of disinfection or sterilization in the required place in a non-contact, non-invasive and economical way.Therefore, alongside conventional (photo)chemical and thermal approaches, significant efforts have recently been devoted to developing a technology for selective inactivation of microorganisms using femtosecond laser pulses in the mid-infrared (mid-IR) range. This method acts directly on selected functional structural components of bacterial cells, without bulk heating of the entire bacterium. Using Pseudomonas aeruginosa as a model organism, it has been demonstrated that the high inactivation efficiency achieved with mid-IR femtosecond laser pulses at the wavelengths of 3.4 and 6 μm, selectively absorbed by the carbohydrate backbone and by proteins/nucleic acids, respectively, is associated with the resultant conformational changes in the structure of proteins, DNA, and RNA within the bacterial cell. Furthermore, femtosecond laser radiation at a wavelength of 6 μm can effectively inactivate bacteria even through a polyethylene film, i. e., without direct air contact.
