A Cooled Metal Diffraction Grating for Attenuating Laser Radiation

Measurement Techniques Aims and scope

The permissible heating temperature for a specified change in the radiation attenuation coefficient is estimated qualitatively for a fine water-cooled copper diffraction grating, used as a laser radiation attenuator. The maximum temperatures are calculated as a function of the geometrical parameters, the power of the cooling system and the radiation absorbed. It is shown that the cooled grating can be used as a calibrated laser radiation attenuator at a wavelength of about 1 μm and a power of 10–20 kW.
