Origin

Late Middle English: from Latin pulsus 'beating', from pellere 'to drive, beat'.

appeal from Middle English:
Recorded first in legal contexts, appeal comes via Old French from Latin appellare ‘to address, accost, call upon’. Peal (Late Middle English) is a shortening of appeal, perhaps from the call to prayers of a ringing bell. The base of appeal is Latin pellere ‘to drive’, found also in compel ‘drive together’; dispel ‘drive apart’; expel ‘drive out’; impel ‘drive towards’; and impulsive; propel ‘drive forwards’; repel ‘drive back’, all Late Middle English. It is also the source of the pulse (Middle English) that you can feel on your wrist and is related to push (Middle English). The other kind of pulse, an edible seed, is a different word, which comes via Old French from Latin puls ‘porridge of meal or pulse’, related to the sources of both pollen and powder.

The technique uses extremely short pulses of intense laser light to focus energy in a very small volume. During the course of the laser pulse, the electric field of the light wave oscillates about a dozen times.
