Sensitivity of intracavity filtering schemes for detecting gravitational waves [PDF]
, 2014 We consider enhancing the sensitivity of future gravitational-wave detectors by adding optical filters inside the signal-recycling cavity -- an intracavity filtering scheme, which coherently feeds the sideband signal back to the interferometer with a ...

FCN-Based Carrier Signal Detection in Broadband Power Spectrum
IEEE Access, 2020 Carrier signal detection has been a problem for a long time, which is the first step for blind signal processing. In this paper, we propose a new method for carrier signal detection in the broadband power spectrum based on the fully convolutional network

Broadband phase coherence between an ultrafast laser and an OPO using lock-to-zero CEO stabilization [PDF]
, 2012 The carrier-envelope-offset frequencies of the pump, signal, idler and related second-harmonic and sum-frequency mixing pulses have been locked to 0 Hz in a 20-fs-Ti: sapphire-pumped optical parametric oscillator, satisfying a critical prerequisite for ...

Evidence against a strong thermal inversion in HD 209458 b from high-dispersion spectroscopy [PDF]
, 2015 Broadband secondary-eclipse measurements of hot Jupiters have indicated the existence of atmospheric thermal inversions, but their presence is difficult to determine from broadband measurements because of degeneracies between molecular abundances and ...
