Optimized thermal control of a dual-wavelength-resonant nonlinear cavity
Fabian Meylahn, Henning Vahlbruch, Benno Willke
Optical resonator-enhanced nonlinear interactions are of great importance for the efficient generation of continuous-wave second harmonic generation, optical parametric oscillation…
Characterization of non-planar ring oscillators at a wavelength of 1064 nm for high precision metrology
Henning Vahlbruch, Fabian Meylahn, Benno Willke
Ultra-stable laser light is essential for high-precision interferometric measurements, in particular for the next generation of gravitational wave detectors, where high power laser…
Design and Performance of the ALPS II Regeneration Cavity
Todd Kozlowski, Li-Wei Wei, Aaron D. Spector +12
The Regeneration Cavity (RC) is a critical component of the Any Light Particle Search II (ALPS II) experiment. It increases the signal from possible axions and axion-like particles…
30 W ultra-stable laser light at 2128 nm for future gravitational-wave observatories
Julian Gurs, Nina Bode, Christian Darsow-Fromm +5
Thermal noise of the dielectric mirror coatings can limit laser-optical high-precision measurements. Coatings made of amorphous silicon and silicon nitride could provide a remedy f…
Passive Laser Power Stabilization via an Optical Spring
Torrey Cullen, Scott Aronson, Ron Pagano +8
Metrology experiments can be limited by the noise produced by the laser involved via small fluctuations in the laser's power or frequency. Typically, active power stabilization sch…
Quantum correlation measurement of laser power noise below shot noise
Jasper Robert Venneberg, Benno Willke
In this Letter, the quantum correlation measurement technique as a method of power noise monitoring is investigated. Its principal idea of correlating two photodetector signals is…
