Carbon monoxide sealed-off laser with operated dispersive cavity for medicine, ecology, active media and material study

摘要

Rather powerful output-stabilized sealed-off cw CO-lasers tunable over lines in a wide spectral range find ever expanding applications to solving numerous problem sets in ecology monitoring, medicine, spectroscopy, metrology, nonlinear optics, communication systems, laser chemistry, diagnostics of active media of high-power CO lasers and other areas. We have created an automatic output-stabilized CO-laser model tunable within a broad spectral range (～300sm~(-1)) and based on a sealed-off (i.e. without need for mixture flow and re-filling) active element. The main model characteristics are: 1. total of lines to be selected for single-wave generation - about 90; 2. tuning order - regular or irregular - to be set manually or under the program guidance and operated by computer; 3. cw power in single strong spectral line - up to 2,000 mW; 4. possibility to operate both at negative and room temperatures; 5. possibility to operate on isotopically replaced molecule CO; 6. long-lasting output power instability-better than 1%; 7. radiation source structure - with enhanced anti-acoustic resistivity; 8. service life- several thousands of hours (about 3,000-5,000).
