概要	This paper reveals one of the primary chemical processes in femtosecond filaments. Reduction yields from Eu³⁺ to Eu²⁺ by focused femtosecond 800 nm pulses in ethanol solution were determined to be 0.021 (Eu²⁺ mole- cule/800 nm photon absorbed) or 0.14 (micro mol/ absorbed laser energy(J)) under single filament conditions. The Eu³⁺ captured an electron which was formed by filamentation, leading to Eu²⁺. About half of the solvated electrons that initially survived were estimated to be captured by Eu³⁺. Halogen ions are found to make a contribution to femtosecond pulse absorption with an increasing tendency with Cl < Br < I.
