How To Use femtosecond In A Sentence
- Since the extra energy being transferred from one molecule to the next changes the way each absorbs and emits light, the flow of energy can be followed through optical spectroscopy, resolved on a femtosecond timescale.
- With pulse widths measured in picoseconds and femtoseconds, these lasers apply cutting energy for such brief periods of time that they don't create troublesome heat-effect zones.
- Each laser pulse packs a 220-millijoule punch into just 60 femtoseconds – an intensity “equivalent to the power of 1000 power plants,” says Kasparian. Scientists Create Laser to Generate Clouds that Could Trigger Rain on Demand | Impact Lab
- The initial laser pulse measures 10 femtoseconds.
- The other theory contends this conversion takes much longer, about 500 femtoseconds.
- Suslick counters that because chemical dissociations occur in mere femtoseconds, reactions would have been well underway even in the acetone bubbles.
- Ultrafast lasers operate with pulses ranging from tens of femtoseconds to a few picoseconds.
- By measuring the emission time of the photoelectrons using the streak method, we have been able to determine both the duration and the chirp of the sub-femtosecond x-ray pulse.
- If you want to study this motion, you need femtosecond pulses of light.
- Femtosecond x-rays could shed new light on these coherent phonons by providing direct information about atomic displacements and enabling us to map out the energy transfer between vibrational modes and vibrational damping.
