Thermodynamical fluctuations and photo-thermal shot noise in gravitational wave antennae

, 1999
Thermodynamical fluctuations of temperature in mirrors of gravitational wave antennae are transformed through thermal expansion coefficient into additional noise.

Quantum dissipative effects in moving imperfect mirrors: sidewise and normal motions

, 2011
We extend our previous work on the functional approach to the dynamical Casimir effect, to compute dissipative effects due to the relative motion of two flat, parallel, imperfect mirrors in vacuum.

Casimir Force for Absorbing Media in an Open Quantum System Framework: Scalar Model [PDF]

, 2011
In this article we compute the Casimir force between two finite-width mirrors at finite temperature, working in a simplified model in 1+1 dimensions. The mirrors, considered as dissipative media, are modeled by a continuous set of harmonic oscillators ...

A New Family of Light Beams and Mirror Shapes for Future LIGO Interferometers [PDF]

, 2004
Advanced LIGO's present baseline design uses arm cavities with Gaussian light beams supported by spherical mirrors. Because Gaussian beams have large intensity gradients in regions of high intensity, they average poorly over fluctuating bumps and valleys

Improved surface quality of anisotropically etched silicon {111} planes for mm-scale integrated optics

, 2013
We have studied the surface quality of millimeter-scale optical mirrors produced by etching CZ and FZ silicon wafers in potassium hydroxide to expose the $\{111\}$ planes.

Notes on moving mirrors [PDF]

, 2001
The Davies-Fulling (DF) model describes the scattering of a massless field by a non-inertial mirror in two dimensions. In this paper, we generalize this model in two different ways. First, we consider partially reflecting mirrors.
