Structure and Lattice Dynamics of RE3Al5O12 (RE = Gd–Lu, Y) Rare-Earth Garnets: Ab Initio Calculation

Autor: V. A. Chernyshev, A. V. Serdtsev

Publikováno v: Optics and Spectroscopy. 125:646-654

Rare-earth garnets with the general formula RE3Al5O12 (RE = La–Lu, Y) are investigated in the MO LCAO approximation. The phonon spectrum of Y3Al5O12 at the Γ point is calculated. Fundamental vibrations in the structure of Y3Al5O12 are assigned bas

Measurement of optical absorption in polycrystalline CVD diamond plates by the phase photothermal method at a wavelength of 10.6 μm

Autor: A. V. Khomich, A V Savel'ev, Vitali I. Konov, V. G. Ralchenko, A. Yu. Luk’yanov, P. V. Volkov, E V Serdtsev

Publikováno v: Quantum Electronics. 38:1171-1178

A highly-efficient phase photothermal method is developed for quantitative measurements of the small optical absorption coefficient in thin plates made of highly transparent materials in which bulk losses significantly exceed surface losses. The bulk
