摘要：

We have applied laser calorimetry to the measurement of optical absorption in mono-crystalline sapphire at cryogenic temperatures. Sapphire is a promising candidate for the mirror substrates of the large-scale cryogenic gravitational wave telescope, The optical absorption coefficients of different sapphire samples at a wavelength of 1.064 mum at 5 K were found to average 90 ppm/cm.
