Abstract
Resistance of a water-cooled polycrystalline diamond window is experimentally studied in the beam of the 10-kW fiber laser. The irradiated zones are 4 and 0.4 mm in diameter. It is shown that the transmitted beam is not distorted when the power density increases to 7 MW cm−2. It is found out that the temperature difference of a few hundreds of degrees between the center of the diamond window and its water-cooled edge does not deteriorate the distribution quality of the laser beam transmitted through the window, which allows the arising thermal lens to be corrected.
