A mechanical shutter enabled performing irradiation cycles, which during the experiments below claimed experienced one s period and a couple of s dim time separation. The probe beam originates from the reduced-electric power He-Ne laser (λ�?�?33 nm) concentrated to some waist of 20 µm and counter propagating with regard to https://andymflwc.therainblog.com/31488606/the-basic-principles-of-lithium-niobate-crystal
