A mechanical shutter enabled carrying out irradiation cycles, which during the experiments in this article documented had 1 s duration and a pair of s dark time separation. The probe beam originates from the lower-electrical power He-Ne laser (λ�?�?33 nm) focused to the waist of 20 µm and counter propagating with regard to the eco-fri
