Laser Development and Stabilisation for Next-Generation Gravitational Wave Detectors

Design and stabilization of high-power laser systems for next generation Gravitational Wave Detectors.

Contributions to QuantumFrontiers

  • Power noise sensing below the quantum limit via the quantum-correlation-method and squeezed light assisted power-noise detection.
  • Opto-mechanical sub-shot noise sensing of power fluctuations required for the laser stabilization of next generation gravitational wave detectors.
  • Creation of a worldwide leading collaboration for GWD laser development and their stabilization.

Collaborative Innovation

Power scaling concepts for single-frequency fibre amplifiers at 1064 nm, 1550 nm and 2000 nm (laser development group, LZH / laser stabilization team, AEI, LUH)

  • designing, fabricating and testing all-fibre amplifier concepts for GWDs
  • optimizing the free-running noise performance of these lasers
  • investigating hybrid solid-state fiber-amplifier systems
  • designing the control systems required for the coherent combination of two high power beams
  • coherent combination of multiple high-power lasers

Laser stabilisation for 3rd generation gravitational wave detectors (laser development group, LZH / laser stabilization team, AEI, LUH)

  • development of shot-noise-limited sensing of laser frequency, power and beam pointing fluctuations
  • analysis and mitigation of the influence of scattered light in sensing schemes
  • development of laser stabilization schemes with high-bandwidth fibre-actuators at 1550nm and 1064nm
  • improved sub-shot noise power sensing via the combination of squeezed light and the optical AC-coupling technique for laser power stabilization
  • laser power stabilization via back-action free interferometric sensing of power fluctuations with micro-oscillator mirrors
  • simulations to derive the laser stability requirement of next generation GWDs
  • advancing future integration of the displacement sensing interferometers developed for back-action free power noise measurements as sensors in the sophisticated power stabilization loops of future GWDs (Kroker, TUBS / Heurs AEI, LUH / Willke AEI, LUH)
