Meanings of higher photon in English

The use of a modulated fibre shifts the energy spectrum of the high-harmonic light to significantly higher photon energies than would otherwise be possible.

However, at higher photon flux densities the electron transport rate decreased in the under-soil shoot parts due to inactivation of the PSII reaction centers.

Higher photon energies further aggravate the outcome by producing longer second build-up regions beyond the cavity.
