Abstract

An optical scheme of an optical parametric oscillator (OPO) with a common pumping based on a pulsed YAG:Nd³⁺ laser (λ=1.064 μm) with a ring resonator based on an active element made of a lithium niobate crystal (LiNbO3), which performs frequency tuning in the near and mid-IR wavelength ranges, is presented. waves (1.41–4.24 μm). A scheme is described and the technical characteristics of a broadband spectrometer developed on the basis of this OPO for medical research based on differential absorption spectroscopy are described. The results of calculation of spectroscopic parameters of the drug ciprofloxacin are presented. It is shown that the developed spectrometer with a tunable radiation frequency makes it possible to confidently detect a large number of organic formations, to identify in them the presence of an increased content of other hazardous impurities that pose a potential threat to health. This method is also applicable to the analysis of human blood components.
