Homework Help: Maximize output intensity -- laser

  1. Mar 27, 2016 #1
    1. The problem statement, all variables and given/known data
    Show that the output coupling that maximizes output intensity (Iout=0.5tIsat(2gl/(t+s) -1) is given by t=sqrt(2gls)-s

    2. Relevant equations


    3. The attempt at a solution
    Iout/Isat=0.5tgl/(t+s)-0.5t
    1=0.5tgl/(t+s)-0.5t
    1+0.5t=0.5tgl(t+s)
    (t+s)+0.5t(t+s)=tgl
    this gives me a really long equation. Is it true that for maximum output coupling, Iout/Isat=1?
