A mechanical shutter enabled undertaking irradiation cycles, which during the experiments listed here described experienced 1 s period and a couple of s dark time separation. The probe beam originates from the reduced-electrical power He-Ne laser (λ�?�?33 nm) focused to the waistline of 20 µm and counter propagating with respect https://lithium-niobate-crystal02356.webdesign96.com/33050420/lithium-niobate-crystal-an-overview
