Confocal Fabry-Perot interferometer for frequency stabilization of laser [PDF]
, 2011 The frequency shift of laser source of Doppler lidar is required in the range of a few megahertzs. To satisfy this demand, a confocal Fabry-Perot (F-P) interferometer was manufactured as the frequency standard for frequency stabilization. After analyzing

Stability of Continuously Pumped Atom Lasers [PDF]
Physical Review Letters, 2002 A multimode model of a continuously pumped atom laser is shown to be unstable below a critical value of the scattering length. Above the critical scattering length, the atom laser reaches a steady state, the stability of which increases with pumping. Below this limit the laser does not reach a steady state. This instability results from the competition

High-precision and fast-response laser power stabilization system for cold atom experiments
AIP Advances, 2018 An innovative and practical scheme of building laser power stabilization system is proposed by using external-control method. A high-speed Field Programmable Gate Array (FPGA) is used as real-time controller, which makes the closed-loop control period of

FEBS Letters, EarlyView.Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.
