Fluence

The fluence produces by a laser is, by definition, the energy delivered by a laser pulse ( $E_{pulse}$ ) per surface unit ( $S$ ) and it is given in J/cm2.

The function $E_{pulse}$ is defined as :

E_{pulse}={\frac {\overline {P}}{f}}\,

Where ( ${\overline {P}}$ ) is the average power and is measured with the laser sensor power measurement and the repetion rate ( $f$ ) is set in the settings.

The fluence is therefore determinate as such :

Fluence={\frac {E_{pulse}}{S}}\,
