As part of the research on thermal noise reduction in gravitational-wave detectors, we experimentally demonstrate conversion a fundamental ${\mathrm{TEM}}_{00}$ laser mode at 1064 nm to higher-order Hermite-Gaussian modes (HG) arbitrary order via commercially available liquid crystal spatial light modulator. We particularly studied ${\mathrm{HG}}_{5,5}/{\mathrm{HG}}_{10,10}/{\mathrm{HG}}_{15,15...
