Improving laser energy measurement is a challenging task. Pyroelectric crystalline energy sensors used in laser energy measurements have a working principle that absorbs the heat of incoming light. Therefore, it is very important to measure the heat transfer in the incoming laser beam with maximum efficiency. The condition of the black sensor coating used to maximize this efficiency plays a leading role in the measurements. By means of laser energy sensor calibration measuring setup, the energy of the pulsed laser source at a wavelength of 1064 nm and a frequency of 20 Hz was measured with damaged and undamaged black sensor coatings. The present study may provide useful guidance into the understanding of black coatings of the detectors to use in laser energy calibrations.
