- LITHIUM NIOBATE CRYSTAL - AN OVERVIEW

A mechanical shutter enabled undertaking irradiation cycles, which from the experiments listed here described had 1 s period and 2 s dark time separation. The probe beam originates from the low-ability He-Ne laser (λ�?�?33 nm) targeted into a waistline of twenty µm and counter propagating with respect for the green pump beam. Probe po
