Marta Csatári is an optical researcher identified by the byline of a2003 multipass optical amplifier study with Ian N. Ross and Steve Hutchins. The experiment combined substantial saturated optical gain with measurements of output stability.^[ref]

One reported quantity is the average output intensity during a pulse train,7kilowatts per square centimeter. That wording matters: an average during a train is not automatically an average over the whole operating cycle.^[ref]

For an original conversion example, suppose that intensity is uniform across an illuminated area of1square millimeter. Since $1\mathrm{m}{\mathrm{m}}^2=0.01\mathrm{c}{\mathrm{m}}^2$,If the train occupies one tenth of a repeated cycle and the output is negligible between trains, the whole-cycle average becomes7watts. The area and duty fraction are stipulated here, not taken from the experiment.

The example distinguishes three descriptions: intensity per unit area, total power and the time interval over which either is averaged. Comparing amplifier results requires those definitions alongside the gain and stability figures. A large numerical intensity alone does not specify the total delivered energy or the long-term average output.
