WebThe stimulated Brillouin scattering (SBS) reflectivity of bulk fused-silica glass is measured at the wavelength of 1.06 mm. At long pulse pumping using a longer focusing lens, a fused-silica glass shows high SBS reflectivity of approximately over 95% with no damage observation at a pumping energy of 380 mJ in a pulse duration of 15 ns. WebVery high reflectivity can be obtained between 0 and 45 degrees angle of incidence. These mirrors provide high reflectance with limited variation over a broad range of wavelengths. The dielectric multilayer coating makes the mirror surface highly resistant to scratches and allows for wiping for cleaning.
