Paper Abstract

CO-lasers on the basis of sealed-off active elements (SAE) with an average operational life of ~3000 hours nave a simple design and are cost-effective. They don't need gas blow off and cryogenic equipment, as well as the system of toxic gas evacuation etc. Generally, sealed-off active elements are operated at the temperatures of the cooling agent of 10°C<t<15°C. Cryogenic cooling is impossible for them, so it is interesting to perform optimization of the laser parameters at the tolerable for SAE negative temperatures. There has been performed the research on the basic output parameter of the automated modified CO-laser, which is applicable for research in medicine, ecology, active media and material study and which we described earlier, at negative temperatures of SAE up to t ~-40 °C. These measurements were made using an inexpensive standalone cooling system ("Haake Circulators"). The measurements have shown that both the width of area of spectrum modification and the power of generation at separate lines go up as the degree of cooling grows.
