Optical Amplitude Limiting in Gallium Nitride: Enhanced Sensitivity at Higher Photon Energies

It has been observed that as photon energy increases, the optical amplitude limiting effect is more likely to occur at low peak power densities. This is due to the wide bandgap characteristic of gallium nitride, which makes it sensitive to high-energy photons. The occurrence of optical amplitude limiting effect is more probable at low peak power densities as the photon energy increases. This is attributed to the wide bandgap property of gallium nitride, which renders it sensitive to high-energy photons.
