Measurement of Thermo-Elastic Deformation of an Optic using a Polarization Based Shearing Interferometer
Peter Beyersdorf, Mark Cordier
A shearing interferometer is presented which uses polarization control to shear the wavefront and to modulate the interference pattern. The shear is generated by spatial walk-off i…
Input spectrum for heterodyne detection in advanced gravitational wave detectors without non-stationary shot-noise
Peter T. Beyersdorf
Future interferometric gravitational wave detectors will make use of the coupling between shot noise and radiation pressure noise that produces a squeezed output for the quantum no…
High Resolution Polar Kerr Effect Measurements of Sr2RuO4: Evidence for Broken Time Reversal Symmetry in the Superconducting State
Jing Xia, Maeno Yoshiteru, Peter T. Beyersdorf +2
Polar Kerr effect in the spin-triplet superconductor Sr2RuO4 was measured with high precision using a Sagnac interferometer with a zero-area Sagnac loop. We observed non-zero Kerr…
Modified Sagnac interferometer for high-sensitivity magneto-optic measurements atcryogenic temperatures
Jing Xia, Peter T. Beyersdorf, Martin M. Fejer +1
We describe a geometry for a Sagnac interferometer with a zero-area Sagnac loop for measuring magneto-optic Kerr effect (MOKE) at cryogenic temperatures. The apparatus is capable o…
Observation results by the TAMA300 detector on gravitational wave bursts from stellar-core collapses
Masaki Ando, Koji Arai, Youichi Aso +19
We present data-analysis schemes and results of observations with the TAMA300 gravitational-wave detector, targeting burst signals from stellar-core collapse events. In analyses fo…
