- Also known as PPFD, photosynthetic photon flux density.
Examples

MU naughty HA common unit for flux density is the Gauss.

-
So PFD stands for photosynthetic photon flux density, which is essentially the density of light particles that hit a measured area.
-
The scientist measured the flux density to determine how much energy was passing through the surface of the material.
-
To calculate the flux density, we divided the total energy passing through the area by the size of that area.

Morphology
The MWE's meaning is directly compositional from 'flux' (rate at which energy or particles pass through) combined with 'density' (quantity per unit area or volume), so a learner who knows both constituents can infer 'rate per unit area' or similar technical sense. Although the term is chiefly used in physics, its noun+noun composition follows regular compositional patterns and is cross-linguistically transparent rather than idiomatic.
Etymology
Flux density combines two clear images: flux, meaning a flow of particles or energy, and density, meaning how much is packed into an area. Imagine many tiny particles or arrows moving through a small net and count how many pass through each square every second; that picture shows why flux density means 'the amount of flow per area'.
