light as charge dispersion
But what I was thinking was that a measurable amount of pressure is detectable at any surface to which light is applied, but also that light is the result of field compression, collapse, or a potential drop,…” -web
No argument there.
One might consider some “compression, collapse or …drop” as the longitudinal vectors of a light ‘beam’,
which seem always to manifest along with a transverse component as well.
These composite radiations are observed to relay spin and (angular/orbital) momentum onto intersecting bits of matter and so are lasers routinely used to squeeze, relax, deflect or otherwise manipulate, on a nano scale.
A cross-sectional image of a piezo~photonic impulse (hammerhead) would be the two at top of this page.

Or, imagining it with some depth, as a cymatic evolution over a duration.
In this particular instance, the pulse conveys spin which, depending on
rate of precession about its longitudinal axis, expresses frequency. [There may be no such thing as light free of spin/polarization, unless it’s the mythical clear light, who knows?]
Upon encounter with plasma or some dielectric at electron scale, an excitation or ‘phonon’ is generated
(perhaps at the electron’s magneto-sheath where double-layer interface ‘zones’ electrically pinch), and is imparted its own quantum of momentum, that then may be ejected to propagate as a plasmon/photon [
nano-quasar scale].
All ammo for the piezo-photonic physicist.
