This final report describes measurements of the thermal conductivity of single crystal alumina from 1 to 70 K and the effect of electron irradiation, and of the thermal conductivity and ultrasonic attenuation of lithium niobate. Point defect scattering of phonons was also studied through lattice ...

where Cp and K are the effective heat capacity and effective thermal conductivity of the cavity material, respectively. I represents the optical power that actually heats the cavity, and δλ is the mode linewidth of the cold cavity. The first term of Eq. (2) represents the heat generated ...
Hence, novel material of optical cavity with high elastic modulus and large conductivity is explored to narrow the laser linewidth8. Moreover, technologies for particle cooling and trapping, e.g. optical lattice with magic wavelength cooling, have been continuously improved to obtain narrower and ...
The surface morphologies of the damaged crystals were examined under an optical microscope and the nature of damage identified. The Vicker’s microhardness was determined at a load of 98.07 mN. The thermal transport properties, thermal diffusivity (α), thermal effusivity (e), thermal conductivity ...
