Calculate the mean photon flux density and the average number of photons in a 1064nm laser with a 7ns pulse width and a 1W peak power (peak power is defined as the laser power measured over one pulse). What would the peak power be for a pulse with the same number of photons if the wavelength was 266nm?

Quantized and total photon energy The particle characteristics of electromagnetic radiation are responsible for the quantized behavior of light energy. This behavior explains the results of varying the intensity and wavelength for an observed photoelectric effect, which describes the emission of electrons when light shines on a metal surface. If light only exhibited a purely wavelike behavior, then either increasing the intensity or decreasing the wavelength would both increase the rate at which electron are emitted. However, monochromatic light of...
