Optical Frequency Standards and Measurements
We describe the performance characteristics and frequency measurements of two high-accuracy high-stability lasercooled atomic frequency standards. One is a 657-nm (456-THz) reference using magneto-optically trapped Ca atoms, and the other is a 282-nm (1064-THz) reference based on a single Hg ion confined in an RF-Paul trap. A femtosecond mode-locked laser combined with a nonlinear microstructur...
متن کاملSequences with Minimal Time-Frequency Uncertainty
A central problem in signal processing and communications is to design signals that are compact both in time and frequency. Heisenberg’s uncertainty principle states that a given function cannot be arbitrarily compact both in time and frequency, defining an “uncertainty” lower bound. Taking the variance as a measure of localization in time and frequency, Gaussian functions reach this bound for ...
متن کاملUncertainty, information and time-frequency distributions *
The well-known uncertaintly principle is often invoked in signal processing. It is also often considered to have the same implications in signal analysis as does the uncertainty principle in quantum mechanics. The uncertainty principle is often incorrectly interpreted to mean that one cannot locate the time-frequency coordinates of a signal with arbitrarily good precision, since, in quantum mec...
متن کاملOptical Frequency Combs: From Frequency Metrology to Optical Phase Control
The merging of continuous wave laser-based precision optical-frequency metrology with mode-locked ultrafast lasers has led to precision control of the visible and near-infrared frequency spectrum produced by mode-locked lasers. Such a phase-controlled mode-locked laser forms the foundation of a “femtosecond optical-frequency comb generator” with a regular comb of sharp lines with well-defined f...
متن کاملOptical parametric oscillators and precision optical frequency measurements
We report experimental results of frequency tuning, stabilization, and beat-note phase noise measurements of a type-II phase-matched potassium titanyl phosphate (KTP) doubly resonant optical parametric oscillator (OPO). Three types of OPO cavity design were constructed and experimented for their mechanical stability and frequency tunability. Four tuning elements were employed in our 2-element a...
