Titania-doped tantala/silica coatings for gravitational-wave detection (2007)
Harry, Gregory M., Abernathy, Matthew R., Becerra-Toledo, Andres E., Armandula, Helena, Black, Eric, Dooley, Kate, ...
Reducing thermal noise from optical coatings is crucial to reaching the required sensitivity in next generation interferometric gravitational-wave detectors. Here we show that adding TiO2 to Ta2O5 in...

Harry, Gregory M., Abernathy, Matthew R., Becerra-Toledo, Andres E., Armandula, Helena, Black, Eric, Dooley, Kate, ...
Reducing thermal noise from optical coatings is crucial to reaching the required sensitivity in next generation interferometric gravitational-waves detectors. Here we show that adding TiO$_2$ to...
Xia, Jing, Beyersdorf, Peter T., Fejer, Martin M., Kapitulnik, Aharon
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 of measuring...
Thermal noise from optical coatings in gravitational wave detectors (2006)
Harry, Gregory M., Armandula, Helena, Black, Eric, Crooks, D. R. M., Cagnoli, Gianpietro, Hough, Jim, ...
Gravitational waves are a prediction of Einstein's general theory of relativity. These waves are created by massive objects, like neutron stars or black holes, oscillating at speeds appreciable to...
Beausoleil, Raymond G., Gustafson, Eric K., Fejer, Martin M., D'Ambrosio, Erika, Kells, William, Camp, Jordan
We develop a steady-state analytical and numerical model of the optical response of power-recycled Fabry-Perot Michelson laser gravitational-wave detectors to nonlinear thermal focusing in optical...
Mechanical Loss in Tantala/Silica Dielectric Mirror Coatings (2003)
Penn, Steven D., Sneddon, Peter H., Armandula, Helena, Betzwieser, Joseph C., Cagnoli, Gianpietro, Camp, Jordan, ...
Current interferometric gravitational wave detectors use test masses with mirror coatings formed from multiple layers of dielectric materials, most commonly alternating layers of SiO2 (silica) and...
Development of High Average Power Nonlinear Frequency Conversion Devices (2003)
Fejer, Martin M., Route, Robert K.
This program developed microstructured nonlinear optical materials and quasi-phasematched devices based on those materials. The two material systems investigated, periodically-poled ferroelectrics,...
Harry, Gregory M., Gretarsson, Andri M., Saulson, Peter R., Penn, Steven D., Startin, William J., Kittelberger, Scott, ...
We report on thermal noise from the internal friction of dielectric coatings made from alternating layers of Ta2O5 and SiO2 deposited on fused silica substrates. We present calculations of the...
Measurement of Birefringence of Low-Loss, High-Reflectance Coating of M-Axis Sapphire (2001)
Camp, Jordan B., Kells, William, Fejer, Martin M., Gustafson, Eric
The birefringence of a low-loss, high-reflectance coating applied to an 8-cm-diameter sapphire crystal grown in the m-axis direction has been mapped. By monitoring the transmission of a high-finesse...
Diode-Laser-Pumped Optical Parametric Oscillator. (1997)
Cimolino, Marc C., Sjaarda-Cornish, Carrie, Byer, Robert, Fejer, Martin M., Eckardt, Robert C.
This report describes the first operation of a CW directly diode-pumped optical parametric oscillator using periodically poled lithium niobate as a nonlinear medium. Degenerate oscillation of a...
