WebApr 2, 2016 · Sorted by: 6. The electric field strength is related to the power of the laser by the Poynting vector. This is given by: S = E × H. and the magnitude of S is the power. Assuming we can treat your laser as a plane wave (which seems reasonable) then E and H are at right angles so the power is simply: P = E H. WebJul 21, 2024 · The amplitude of a wave will decrease if there is absorption of the wave's energy. This is true for any wave, E&M, sound, etc. I'm not sure what pictures you see on the internet related to this, but if the E&M wave is propagating through vacuum, then it's amplitude will not decrease. So what counts as absorption? how do you prep aluminum for painting
