Incoherent irradiance
Webwere much smaller, where the irradiance is more uniform, the monolithic aperture would be the clear winner and adding incoherent beamlets/subapertures, each with the equal output power, only decreases the target bucket peak irradiance when the overall aperture area is not correspondingly increased. Based on Eq. WebThe Irradiance (continued) The irradiance (or intensity) is the magnitude of the time average of the Poynting vector: Since the time-dependence of S is given by a cos 2, we must take the time average of this function. 2 2 ( ) (,) cos= × ⋅ − +ε ω θ 0 0 r r r rr S r t c E B k r t The average of cos 2(x) is ½:
