A mechanical shutter enabled doing irradiation cycles, which while in the experiments right here documented experienced 1 s period and 2 s dark time separation. The probe beam originates from the very low-energy He-Ne laser (λ�?�?33 nm) centered to a waistline of twenty µm and counter propagating with regard on https://lithium-niobate-crystal86306.izrablog.com/32986128/lithium-niobate-crystal-no-further-a-mystery
