The influence of low‐intensity laser radiation (LLR) on the rheological characteristics of human blood has been investigated. The results of the investigation of the blood velocity in the human skin capillaries, the erythrocyte aggregation time, and the spectral width of scattering intensity fluctuations depending on the irradiation time are presented. It has been shown that laser irradiation leads to a decrease in the degree of aggregation of erythrocytes and, accordingly, to an increase in the velocity of blood microcirculation, which can be used for laser therapy and diagnostics and treatment of cardiovascular diseases (CVD). To explain the results obtained, a method of the LLR–biotissue interaction is proposed.

    Abstract. A significantly improved far-infrared laser has been used to generate optically pumped laser emissions from 26 to 150 micro m for CD[sub 3]OH. Using an X-V-pumping geometry, several new laser emissions have been found for CD[sub 3]OH. In addition, an increase in power, by factors from...

    Abstract. Absorption of laser radiation at 193 nm by CO[sub 2] and O[sub 2] was studied at a series of different temperatures up to 1273 K and pressures up to 1 bar. The spectrum for CO[sub 2] was found to be broadband, so that absorption could be fitted to a Beer-Lambert law. On the other hand,...
