LN-Q Kusintha kwa Crystal

Kufotokozera Kwachidule:

LiNbO3 imagwiritsidwa ntchito kwambiri ngati ma electro-optic modulators ndi Q-switches kwa Nd: YAG, Nd: YLF ndi Ti: lasers ya safiro komanso ma modulators a fiber optics. Gome lotsatirali limatchula za kristalo wamba wa LiNbO3 womwe umagwiritsidwa ntchito ngati Q-switch yokhala ndi kusintha kwa EO.

Kuwala kumafalikira mu z-axis ndi malo amagetsi kumagwira ntchito ku x-axis. Ma electro-optic coefficients a LiNbO3 ndi: r33 = 32 pm/V, r31 = 10 pm/V, r22 = 6.8 pm/V pafupipafupi otsika ndi r33 = 31 pm/V, r31= 8.6 pm/V, r22 = 3.4 pm/V pama frequency apamwamba amagetsi. Theka-wave voliyumu: Vπ=λd/(2no3r22L), rc=(ne/no)3r33-r13.LiNbO3 ndi wabwino acousto-optic crystal ndipo amagwiritsidwa ntchito pamwamba acoustic wave (SAW) wafer ndi AO modulators. CASTECH imapereka makhiristo amtundu wa acoustic (SAW) a LiNbO3 m'mipando yopyapyala, ma boules odulidwa, zida zomalizidwa ndi zinthu zopangidwa mwamakonda.
