The effect of electromagnetic waves from the light spectrum and nearby frequencies on the
human body is a topic that has not been studied in detail. Light waves of different …

Marking and engraving of aluminum was carried out by a CuBr (copper bromide) laser
operating at the wavelength of 511 nm with a pulse duration of 30 ns. The reflection was …

A comparison is made between samples marked by writing letters and symbols once, with
these marked by twice but writing with two times greater velocity. As a consequence of the …

A method for contactless temperature measurement with photodetectors in different
operating modes has been developed. It is based on the periodic change of the spectral …

Laser engraving is one of the most commonly used laser procedures for interacting with
laser material. The speed, ease of use and high precision make it an attractive process for …

In the research carried out at the Rezekne Academy of Technology, the technology for color
