This paper analytically and numerically investigates misalignment and mode-mismatch-induced power coupling coefficients and losses as a function of Hermite-Gauss (HG) mode order. We show that higher-order HG modes are more susceptible to beam perturbations when, for example, coupling into optical cavities: the misalignment and mode-mismatch-induced power coupling losses scale linearly and quadratically with respect to the mode indices, respectively. As a result, the mode-mismatch tolerance for… Expand

Prospects of higher-order Laguerre Gauss modes in future gravitational wave detectors
The application of higher-order Laguerre-Gauss (LG) modes in large-scale gravitational wave detectors has recently been proposed. In comparison to the fundamental mode, some higher-orderExpand
Coupling coefficients of an incident wave and the modes of a spherical optical resonator in the case of mismatching and misalignment.
Coupling coefficients describe the excitation of eigenfunctions by an incident wave and an estimate of the residual amounts of misalignment and mismatching is an example of the use of the coupling coefficients. Expand

Automatic alignment of optical interferometers.
A system for automatic alignment of optical interferometers relies on using differential phase modulation to permit the detection of the phase difference between two fundamental-mode Gaussian beams at the output of an interferometer. Expand

The architecture of SymPy is presented, a description of its features, and a discussion of select domain specific submodules are discussed, to become the standard symbolic library for the scientific Python ecosystem. Expand
Higher-order Hermite-Gauss modes for gravitational waves detection
Higher-order Hermite-Gauss modes as a robust flat beam in interferometric gravitational wave detectors
Higher-order Laguerre-Gauss (LG) modes have previously been investigated as a candidate for reducing test-mass thermal noise in ground-based gravitational-wave detectors like Advanced LIGO. It hasExpand
Increased sensitivity of higher-order laser beams to mode mismatches.
This Letter derives explicit factors linking mode-mismatch-induced power losses in Hermite-Gauss optical modes to the losses of the fundamental spatial mode, which should inform mode matching and squeezing requirements for Advanced+ and third generation detectors. Expand
