I have a problem in solving laser rate equation, I need help

  1. Mar 29, 2015 #1
    Hi every one.
    I want to solve the Yb:YAG laser rate equations. I have three differential equation:


    and the boundary conditions are:


    the schematically figure of Yb:YAG crystal is:


    But in the above equations, I am confident the N1 and N0 parameters are changing but I can't recognize how they changed?is there an equation?
