Sentences with phrase «repetition rate»
The phrase "repetition rate" refers to the speed or frequency at which something is repeated. It basically indicates how often an action or event takes place within a particular timeframe. Full definition

A higher repetition rate is also key to using a high - power laser to drive beams of particles.
When we say that, it's because of the rapid repetition rate — we're saying it's small in diameter.
It achieves both high power and a high repetition rate.
Scientists can measure repetition rates in the gigahertz (microwave) range very accurately using high - speed photodiodes, which detect each pulse in turn — and an optical comb would appear to leverage that accuracy up to visible wavelengths.
In addition, Congress has ordered DOE to carry out a program looking into high repetition rate lasers.
A typical repetition rate is around one gigahertz (a billion cycles per second), somewhat slower than modern computer processors.
«If you want to make a device that's of use for particle physics, of use for medical applications, of use for light source applications, you need repetition rate,» explains Wim Leemans, physicist at Berkeley Lab.

«Once we synthesize a pulse at higher repetition rates,» says Leemans, «we will be on our way towards a kilohertz GeV laser plasma accelerator.»
The human eye is deceived because, at a repetition rate of 100 hertz, it can not distinguish between areas where pixels are swapped and where they are not.
Still, the goal of a high - repetition rate, 10 - GeV laser - plasma accelerator that fires a thousand pulses or more per second, is at least five to ten years away, says Leemans.
«At the moment, we have a repetition rate of 20 laser pulses per second.
In the absence of such a wave meter, you can systematically vary the repetition rate and the offset frequency to monitor how the beat frequency changes in response.
Everything is fine if the phase of every pulse in the train is exactly the same, because in that case the comb teeth will be precisely at integer multiples of the repetition rate.
In that case, the comb teeth are shifted in frequency away from the exact integer multiples of the repetition rate by an amount called the offset frequency.
Most mode - locked lasers operate at a repetition rate of 10 gigahertz or less, making that quantity easy to measure against the cesium clock.
Thus, you would know the teeth positions once you had measured the laser's repetition rate.
To know the frequencies of the comb teeth, one must measure that frequency as well as the repetition rate.
Plotted, the spectrum looks like the teeth of a hair comb, spaced at precisely the laser's repetition rate.
Second, mode - locked lasers emit trains of pulses at a very regular rate, called the repetition rate.
Recall that the comb's line spacing is the same as the repetition rate of the pulses producing the comb.
When distributed measurements were performed at 100 points with 10 times averaging, a repetition rate of 100 Hz was verified by tracking a mechanical wave propagating along the fiber.
At first lasing, the laser had a repetition rate of one pulse per second, which will later increase to 27,000 per second.
Our innovative ultrafast products, including a complete line of Ti: Sapphire amplifiers, come at various energies, pulse durations, and repetition rates.

NIF's big glass lasers can only deliver a few shots a day without active cooling, but a power plant will need ignition at a high repetition rate.
A typical pulse repetition rate is 80 MHz, but devices with multi-gigahertz repetition rates are also commercially available, which can be used e.g. as frequency comb sources.
