Cavity optoelectromechanical regenerative amplification.
Cavity optoelectromechanical regenerative amplification is demonstrated. An optical cavity enhances mechanical transduction, allowing sensitive measurement even for heavy oscillators. A 27.3 MHz mechanical mode of a microtoroid was linewidth narrowed to 6.6 ± 1.4 mHz, 30 times smaller than previously achieved with radiation pressure driving in such a system. These results may have applications ...
متن کاملCooling and control of a cavity optoelectromechanical system.
We implement a cavity optoelectromechanical system integrating electrical actuation capabilities of nanoelectromechanical devices with ultrasensitive mechanical transduction achieved via intracavity optomechanical coupling. Electrical gradient forces as large as 0.40 microN are realized, with simultaneous mechanical transduction sensitivity of 1.5x10{-18} m Hz{-1/2} representing a 3 orders of m...
متن کاملMacrorealism inequality for optoelectromechanical systems
We show how to apply the Leggett-Garg inequality to opto-electro-mechanical systems near their quantum ground state. We find that by using a dichotomic quantum nondemolition measurement (via, e.g., an additional circuit-QED measurement device), either on the cavity or on the nano-mechanical system itself, the Leggett-Garg inequality is violated. We argue that only measurements on the mechanical...
متن کاملSpatial structure of broad-area vertical-cavity regenerative amplifiers.
We investigate the spatial structure of broad-area vertical-cavity regenerative amplifiers injected with a homogeneous beam. The emerging patterns have a predominantly sixfold rotational symmetry, verifying the recent prediction of formation of hexagons. The length scale is controllable by means of detuning and follows the prediction for tilted waves.
متن کاملAn alexandrite pumped Nd:glass regenerative amplifier for chirped pulse amplification
For many high field physics studies a laser source capable of producing intensities of 1017 W/cm 2 or greater is necessary. Ideally, such a laser source should be compact and simple so that it is at once reliable and manageable. In order to make the laser as compact as possible it is extremely desirable to use solidstate amplifier materials because of their energy storage capability. If this en...
