The compatibility of higher-order Laguerre-Gauss (LG) modes with interferometric technologies commonly used in gravitational wave detectors is investigated. In this paper, we present the first experimental results concerning the performance of the LG{sub 33} mode in optical resonators. We show that the Pound-Drever-Hall error signal for a LG{sub 33} mode in a linear optical resonator is identical to that of the more commonly used LG{sub 00} mode, and demonstrate the feedback control of the… Expand

Higher-order Laguerre-Gauss modes in (non-) planar four-mirror cavities for future gravitational wave detectors.
It is shown that the current four-mirror cavities of aLIGO are not compatible with Laguerre-Gauss modes due to astigmatism, and it is demonstrated that a non-planar cavity could be used instead as it compensates for theastigmatism and transmits the LG33 mode undisturbed. Expand
The Generation of Higher-order Laguerre-Gauss Optical Beams for High-precision Interferometry
Higher-order Laguerre-Gauss optical beams can be purified and stabilized just as well at a comparably high level with standard interferometry techniques and with the use of standard spherical optics, making them an ideal candidate for application in a future generation of high-precision interferometric experiments.
