Detailed Description
class Elasticity::BoundaryConditions::LaserBeam< Registrars >
A laser beam with Gaussian profile normally incident to the surface.
This boundary condition represents a laser beam with Gaussian profile that exerts pressure normal to the surface of a reflecting material. The pressure we are considering here is
\begin{align} n_i T^{ij} = -n^j \frac{e^{-\frac{r^2}{r_0^2}}}{\pi r_0^2} \end{align}
where \(n_i\) is the unit normal pointing out of the surface, \(r\) is the coordinate distance from the origin in the plane perpendicular to \(n_i\) and \(r_0\) is the "beam width" parameter. The pressure profile and the angle of incidence can be generalized in future work. Note that we follow the convention of [78] and [77] in defining the beam width, and other publications may include a a factor of \(\sqrt{2}\) in its definition.
This boundary condition is used to simulate thermal noise induced in a mirror by the laser, as detailed for instance in [78] and [77]. See also Elasticity::Solutions::HalfSpaceMirror for an analytic solution that involves this boundary condition.
