THE SINGLE BEST STRATEGY TO USE FOR - LITHIUM NIOBATE CRYSTAL

A mechanical shutter enabled doing irradiation cycles, which during the experiments here reported experienced one s length and 2 s dark time separation. The probe beam originates from the very low-electric power He-Ne laser (λ�?�?33 nm) centered to the waist of twenty µm and counter propagating with respect to the eco-friendly pump be
