Laser development and stabilisation for next-generation GWDs

Laser development and stabilisation for next-generation GWDs

ACTIVITIES

Scaling concepts for single-frequency fibre amplifiers at 1064 nm, 1550 nm and 2000 nm

  • design, fabricate and test all fibre amplifier concepts
  • optimise the free-running noise performance of the lasers
  • develope hybrid laser systems based on Nd:YVO solid-state pre-amplifiers followed by high power fiber amplifiers
  • tested hybrid systems and compared to sequential Nd:YVO amplifier chains.
  • coherent combination

 

Laser stabilisation for 3rd generation gravitational wave detectors

  • shot-noise-limited sensing of the relevant laser observables
  • analyse and mitigate the influence of scattered light in sensing schemes
  • develop laser stabilisation schemes with high bandwidth fibre actuators
  • usage of squeezing and AC coupling to laser stabilisation
  • laser stabilisation at 1550nmn, evaluate synergies of combined stabilisation/squeezing setup

COMPETENCES/SERVICES

  • high power lasers
  • laser stabilisation
  • shot noise limited sensing
