LIQUID COOLANT-OPTICAL FILTER FOR SOLID-STATE LASERS

摘要

FIELD: physics.;SUBSTANCE: invention relates to laser technology and specifically to liquid coolants of solid-state lasers (e.g., neodymium or holmium lasers) which are simultaneously an optical filter for ultraviolet (UV) radiation of the laser pumping lamp. The coolant can be used anywhere, where solid-state lasers, having a liquid cooling system with filtration of UV radiation of the pumping lamp, are designed or used. The liquid coolant contains 2-oxy-4-(C7-C9-alkyl)oxybenzophenone, butyl alcohol and octane, with the following content of components, wt %: 2-oxy-4-(C7-C9-alkyl)oxybenzophenone 0.3-0.6, butyl alcohol 35-45, octane - the balance.;EFFECT: longer service life of the laser.
