Improving Beam Quality in Gravitational-Wave Interferometers Illuminated by Higher-Order Laguerre-Gaussian Modes
Liu Tao, Yuefan Guo, Alberto Gatto +5
Higher-order Laguerre-Gaussian (LG) laser modes have been proposed to reduce test-mass thermal noise in laser interferometric gravitational-wave detectors, owing to their more homo…
Beam displacement tolerances on a segmented mirror for higher-order Hermite-Gauss modes
Liu Tao, Nina Brown, Paul Fulda
Odd-indexed higher-order Hermite-Gauss (HG) modes are compatible with 4-quadrant segmented mirrors due to their intensity nulls along the principal axes, which guarantees minimum b…
Power coupling losses for misaligned and mode-mismatched higher-order Hermite-Gauss modes
Liu Tao, Jessica Kelley-Derzon, Anna C. Green +1
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. W…
Higher-order Hermite-Gauss modes as a robust flat beam in interferometric gravitational wave detectors
Liu Tao, Anna C. Green, Paul Fulda
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 Advan…
