Stray light is an issue in any optical instrumentation. It affects the accuracy and resolution of the measurements, or their dynamics, possibly the resolution of images. Methods do exist at component leval (reflectometry, scatterometry) to measure stray light. But the measurement of stray light at system level can be difficult once integration...

As part of the research on thermal noise reduction in gravitational-wave detectors, we experimentally demonstrate the conversion of a fundamental TEM00 laser mode at 1064 nm to higher-order Hermite-Gaussian modes (HG) of arbitrary order via a commercially available liquid crystal spatial light modulator. We particularly studied the...
