“…Parametric oscillatory is a serious problem for gravitational wave detectors, and thus you must have information about the combinations of the optical Stokes and elastic modes that may be candidates for PI [7][8][9][10][11][12][13][14]. The first observation of PI on the Advanced LIGO detectors has been made in 2015 [15], thereby fully confirming the prediction of Braginsky et al [4].…”

“…It is interesting to also consider the performance if the arm cavity power was reduced to 200kW, since high optical power is one of the greatest technical challenges. It is well known that high power introduces thermal aberrations (Zhao et al 2006) and can cause parametric instability (Zhao et al 2005Evans et al 2015). The value of 200kW is chosen because it is comparable to the power levels already achieved in aLIGO.…”

The detection of three black hole binary coalescence events by Advanced LIGO allows the science benefits of future detectors to be evaluated. In this paper we report the science benefits of one or two 8km arm length detectors based on the doubling of key parameters in an advanced LIGO type detector, combined with realisable enhancements. It is shown that the total detection rate for sources similar to those already detected, would increase to ∼ 10 3 -10 5 per year. Within 0.4Gpc we find that around 10 of these events would be localizable to within ∼ 10 −1 deg 2 . This is sufficient to make unique associations or to rule out a direct association with the brightest galaxies in optical surveys (at r-band magnitudes of 17 or above) or for deeper limits (down to r-band magnitudes of 20) yield statistically significant associations. The combination of angular resolution and event rate would benefit precision testing of formation models, cosmic evolution and cosmological studies.

“…Soon thereafter, dynamical backaction cooling, an effect Braginsky predicted [6] to occur for red-detuned laser excitation, was demonstrated [7][8][9]. Although the parametric instability was first analyzed for a single electromagnetic mode coupled to a mechanical oscillator, the effect can also occur for multi-mode systems in which modes are spaced by the mechanical frequencies [10], a scenario in which the parametric oscillator stability in advanced LIGO at the Livingston observatory [11] was observed. Although undesirable in the context of LIGO, the ability to amplify and cool mechanical motion using dynamical backaction is at the heart of the advances in cavity opto-and electromechanics over the past decade [12] that have enabled mechanical systems to be controlled at the quantum level.…”

A maser based on dynamical backaction on microwave light

The work of Braginsky introduced radiation pressure dynamical backaction, in which a mechanical oscillator that is parametrically coupled to an electromagnetic mode can experience a change in its rigidity and its damping rate. The finite cavity electromagnetic decay rate can lead to either amplification or cooling of the mechanical oscillator, and lead in particular to a parametric oscillatory instability, associated with regenerative oscillations of the mechanical oscillator, an effect limiting the circulating power in laser gravitational wave interferometers. These effects implicitly rely on an electromagnetic cavity whose dissipation rate vastly exceeds that of the mechanical oscillator, a condition naturally satisfied in most optomechanical systems. Here we consider the opposite limit, where the mechanical dissipation is engineered to dominate over the electromagnetic one, essentially reversing role of electromagnetic and mechanical degree of freedom. As a result, the electromagnetic field is now subject to dynamical backaction: the mechanical oscillator provides a feedback mechanism which modifies the damping rate of the electromagnetic cavity. We describe this phenomenon in the spirit of Braginsky's original description, invoking finite cavity delay and highlighting the role of dissipation. Building on previous experimental work, we demonstrate this dynamical backaction on light in a superconducting microwave optomechanical circuit. In particular, we drive the system above the parametric instability threshold of the microwave mode, leading to maser action and demonstrate injection locking of the maser, which stabilizes its frequency and reduces its noise.Comment: Manuscript prepared for a special issue of Physics Letters A in memory of V. Braginsk
