Abstract

The paper presents the results on investigations and development of multichannel waveguide CO₂ laser with diffusion cooling of active medium excited by discharge of audio-frequency alternating current. The description of high-power single-mode CO₂ laser with average beam power up to 1 kW is presented. The result of measurement of the laser basic parameters are offered, as well as the outcomes of performances of the laser head with long active zone, operating in waveguide mode. As an example of application of these laser, various capabilities a description of the developed medical system 'Genom' used in the transmyocardial laser revascularization (TMLR) procedure and clinical results of the possibilities of the TMLR in the surgical treatment are presented.
