Difference between steady state intensity and saturation intesity in laser

Question

Can some one explain the diffrence between steady state intensity and saturation intensity in lasers. And diffrence between gain at threshold and gain at steady state,why are these two gain equal?
Thanks

Saturation takes place before than steady state.   At saturation intensity exponential grows of gain convert to linear. When gain and loss become equal then steady state take place.
