  • 0.75 atoms improve the clock signal of 10,000 atoms 
    Kruse, I.; Lange, K.; Peise, J.; Lücke, Bernd; Pezzè, L.; Arlt, Jan J.; Ertmer, Wolfgang; Lisdat, C.; Santos, Luis; Smerzi, A.; Klempt, Carsten (Bellingham, WA : S P I E - International Society for Optical Engineering, 2017)
    Since the pioneering work of Ramsey, atom interferometers are employed for precision metrology, in particular to measure time and to realize the second. In a classical interferometer, an ensemble of atoms is prepared in ...
  • Numerical analysis of LG3,3 second harmonic generation in comparison to the LG0,0 case 
    Heinze, Joscha; Vahlbruch, Henning; Willke, Benno (Washington, DC : OSA - The Optical Society, 2020)
    For coating Brownian thermal noise reduction in future gravitational wave detectors, it is proposed to use light in the helical Laguerre-Gaussian LG3,3 mode instead of the currently used LG0,0 mode. However, the simultaneous ...
  • Quantum-Enhanced Advanced LIGO Detectors in the Era of Gravitational-Wave Astronomy 
    Tse, M.; Yu, H.; Kijbunchoo, N.; Fernandez-Galiana, A.; Dupej, P.; Barsotti, L.; Blair, C.D.; Brown, D.D.; Dwyer, S.E.; Effler, A.; et al.; Bode, N.; Booker, P.; Liu, J.; Meylahn, F.; Willke, B. (College Park, MD : American Physical Society, 2019)
    The Laser Interferometer Gravitational Wave Observatory (LIGO) has been directly detecting gravitational waves from compact binary mergers since 2015. We report on the first use of squeezed vacuum states in the direct ...
  • Utilizing weak pump depletion to stabilize squeezed vacuum states 
    Denker, T.; Schütte, D.; Wimmer, M.H.; Wheatley, T.A.; Huntington, E.H.; Heurs, Michèle (Washington, DC : The Optical Society, 2015)
    We propose and demonstrate a pump-phase locking technique that makes use of weak pump depletion (WPD) - an unavoidable effect that is usually neglected - in a sub-threshold optical parametric oscillator (OPO). We show that ...
