Each pulse lasts less than a millisecond.

The pulse lasted about seven nanoseconds, and the laser spread very slightly with distance.

The discharges from the electric organ occur in a series, or train, of closely spaced pulses each lasting around 0.03 seconds.

If the pulse lasts several vibration seconds, peak pressure is the important quantity.

"Neither pulse lasted long enough to be able to tell, Captain."

This pulse lasted long enough for us to derive a reading of field strength, sir.

The pulse lasts around 10-40 microseconds depending on the laser parameters.

This is true because the pulse lasts about 50 ns, allowing for a maximum of 2x10 events every second.

Each pulse lasts less than a second and takes a picture of a thin slice of the organ or area being studied.

Such pulses may last a few hundred years, and are thought to occur periodically every 10,000 to 100,000 years.
