Dopant Concentration Tolerance +/-0.1% Parallelism <10 arcsec Perpendicularity < 5 arcmin Clear Aperture 95% Surface Quality 10 - 5 scratch & dig Surface Flatness λ/10 @ 633nm Wavefront distorton /=7mm diameter: λ/8 @ 633nm Damage Threshold over 15J/cm2 TEM00, 10ns, 10Hz Pure YLF crystals are transparent within the spectrum band of 0.12 - 7.5 µm, photo-, thermo- and adiation-resistant. The YLF crystals has low non-linear refraction index value and thermo optical constants, which makes theses crystals applicable in research, development, education, production, photonics, optic, laser technology and telecommunications.
