Spectral diffraction lenses that have the same focusing distance for several specified wavelengths are proposed as a basis for a point light source with several specified wavelengths. A spectral diffraction lens designed to focus three wavelengths, 4

Diffractive optical elements for the formation of laser beams with intensity distributions in the form of ring light traps with zero total orbital angular momentum are considered and studied by means of a computational experiment. The beams are forme

We consider the possibility of using generalized lenses in imaging optical systems. We propose using two generalized lenses in a system similar to a Fourier-correlator to obtain a point-to-point mapping, where the second lens is set so that a plane w

We described an experiment on passing Bessel beams through the atmosphere with heat-trolled flows. We showed that at small distances, while passing through the region with a hot air flow, the Bessel beam can be distorted to a complete loss of the str

A new method for forming hypergeometric beams, based on addition of topological charges of the axicon structure with a logarithmic arrangement of bands and topological charges of bands themselves is proposed. The results of a natural experiment confi

This paper examines the spectral properties of a spiral phase plate (SPP) generating orbital angular momentum (OAM) beams. A simple method is proposed for calculating the resulting OAM by measuring only two maximum expansion coefficients. A comparati

In this study, a configuration of a compact imaging objective based on a reflecting annular harmonic lens was proposed. Light propagation through the proposed optical system was comprehensively modeled using a dedicated special program and the ZEMAX
