Offset Lock with 440 GHz Range usingElectro-Optic Modulation

چکیده
Offset locking is a popular method for stabilizing laser frequency, which crucial to many physics experiments. Wide range offset locks are desirable, as they increase the span of usable frequencies in an experiment. Here, we experimentally realize wide-range lock using beat-note setup combined with electro-optic phase modulation. By frequency down-conversion beat note and sidebands generated by modulation, achieve $\pm$ 220.1 GHz fluctuations under 0.1 Hz, enabling optical heterodyne largest known any such lock. The relative simplicity our provides compelling at offsets hundreds range.

Widely tunable laser frequency offset lock with 30 GHz range and 5 THz offset.
We demonstrate a simple and versatile method to greatly extend the tuning range of optical frequency shifting devices, such as acousto-optic modulators (AOMs). We use this method to stabilize the frequency of a tunable narrow-band continuous-wave (CW) laser to a transmission maximum of an external Fabry-Perot interferometer (FPI) with a tunable frequency offset. This is achieved through a servo...
متن کاملTransactional Virtual Memory with Fine-grained Range Lock Support
Lightweighted Recoverable Virtual Memory (RVM) [5] is a software mechanism to support persistent virtual memory regions in the face of system crashes. Regions maintained by RVM are accessed in transactions. RVM can undo all the memory changes in aborted transactions, while committed transactions have their changes written to secondary storages. Therefore transactional atomicity and durability a...
متن کاملDichroic atomic vapor laser lock with multi-gigahertz stabilization range.
A dichroic atomic vapor laser lock (DAVLL) system exploiting buffer-gas-filled millimeter-scale vapor cells is presented. This system offers similar stability as achievable with conventional DAVLL system using bulk vapor cells, but has several important advantages. In addition to its compactness, it may provide continuous stabilization in a multi-gigahertz range around the optical transition. T...
متن کاملP 440 Linkage analysis in english pedigrees with dominant optic atrophy
J7FSULT.S Genethon Microsatelite markers as described by Gyapay et al 1994 were used to map the region 3q-28-qter which has been linked to OPAl by Eiberg et al, 1994. Twelve families were studied. Results with fluoresc:ently labelled primers show evidence for linkage to D3Si265. This is being confirmed using pP radiolabelled markers and the region is being further explored using 0381314 and D3S...
متن کاملAn OFDM Carrier Frequency Offset Estimation Scheme with Wide Fractional Offset Estimation Range
In this paper, we propose a carrier frequency offset (CFO) estimation scheme which is robust to the fractional CFO variation for orthogonal frequency division multiplexing (OFDM) systems. The proposed scheme first performs the envelope equalization process to convert the offset estimation problem to a carrier estimation problem, and then, estimates the integer and fractional parts of CFO by usi...
