Input-output intensity curves for a saturable amplifier off line center. The typical curves of output intensity versus input intensity for a homogeneous single-pass laser amplifier given in this section assume a signal tuned to the atomic line center. Explain clearly (with sketches) exactly how these curves will change, for the same amplifier and the same plot, as the signal frequency is tuned off line center. How will the plot of energy extraction efficiency n versus net power gain G change with the same detuning
