"WebThe saturation fluence is the fluence (energy per unit area) it takes to reduce the initial value to 1/e (≈ 37%) of its initial value. A large saturation fluence can often be compensated by using a tightly focused beam in the absorber. The saturation energy is the saturation fluence times the mode area. " - Optics fluence
