The gain reduction is independent of pulse duration and pulse shape; it only matters how much energy (how many photons) a pulse has. Of course, it is assumed that the pulse duration is short enough that no substantial amount of energy is lost by spontaneous emission. The pulse repetition rate also does not matter; the amplifier or absorption behavior should not depend on what amplification or absorption processes have been done in the past – except under more complicated circumstances, e.g. when heating of the device matters.

When <$N$> passes of a pulse through an amplifier medium are arranged, an effective saturation energy can be defined, which is reduced by a factor <$N$>.

Note that the saturation fluence of a saturable absorber does not depend on the thickness of the absorber layer, unless the thickness is so large that the fluence is reduced substantially within the device.

Enter input values with units, where appropriate. After you have modified some inputs, click the “calc” button to recalculate the output.

Further, the extractable energy also depends on the pulse duration, pulse shape and repetition rate, but above the formula does not consider any of these, but still it can be used for all pulse durations/shapes/reprates?

Usually, the gain or loss is assumed to be small, i.e. input and output pulse energies are similar. (In the case of large gain, the quantity can be related to the input or output pulse energy, leading to different values.)

These quantities can be defined in an analogous way for saturable absorbers. For example, a pulse with a fluence equal to the saturation fluence reduces the saturable loss of a SESAM to <$1/e$> of its initial value.

The saturation energy of a laser gain medium is the pulse energy of an incident short signal pulse which leads to a reduction in the gain to <$1/e$> (≈ 37%) of its initial value. Similarly, the saturation energy of a saturable absorber is defined based on the loss reduction.

where <$h \nu$> is the photon energy at the signal wavelength, <$\sigma_\rm{em}$> and <$\sigma_\rm{abs}$> are the emission and absorption cross-sections at the emission wavelength, and <$A$> is the mode area. The quantity <$\sigma_\rm{abs}$> is zero for four-level gain media (exhibiting no reabsorption on the laser transition) but should not be forgotten for quasi-three-level laser gain media.

Precisely speaking, the mentioned gain or loss reduction refers to the gain or loss directly after the pulse – not to the average gain or loss for the pulse itself. The pulse duration is assumed to be so short (typically shorter than the upper-state lifetime) that both spontaneous emission and the addition of energy from the pump source (for continuous pumping of a laser gain medium) are negligible.
