摘要：

This article gives the results of the measurements of the Institut National de Metrologie (INM) LaseRad cavity reflectance. These measurements were performed at several laser wavelengths: 325 nm, 488 nm, 514 nm, 543 nm, 633 nm and 1550 nm. The comparison of our measurements at 633 nm with those carried out by Cambridge Research & Instrumentation, Inc. (USA) five years ago shows satisfactory agreement. The discrepancy between these two measurements is within the measurement uncertainties in the range of 5 x 10(-5). The change in the reflectance with wavelength is not negligible. The reflectance varies from 2.8 x 10(-4) to 1.10 x 10(-4), according to the wavelength.
