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. WebAt baseline, there were no significant differences between the two groups. The mean follow-up period was 12.5±4.3 months (range, 6–18 months) in the low-fluence group and 13.1±4 months (range, 6–18 months) in the half-dose group ( P =0.568).
