Abstract
The water-cooled copper grating used as a laser radiation attenuator has been studies. The permissible heating temperature within a predetermined range of the attenuation coefficient is estimated qualitatively. The maximum temperatures as functions of geometry, power of cooling systems and absorbed radiation have been calculated. It is shown that the cooled grating can be used as a calibrated laser radiation attenuator with the wavelength ~1 mkm and the beam power ~(10-20) kW.
