LN–Q Chanje Crystal
Deskripsyon Product
Limyè a pwopaje nan aks z ak jaden elektrik aplike nan aks x. Koefisyan elektwo-optik LiNbO3 yo se: r33 = 32 pm/V, r31 = 10 pm/V, r22 = 6.8 pm/V nan frekans ba ak r33 = 31 pm/V, r31= 8.6 pm/V, r22 = 3.4 pm/V nan gwo frekans elektrik. Vòltaj mwatye vag: Vπ=λd/(2no3r22L), rc=(ne/no)3r33-r13.LiNbO3 tou se yon bon kristal acousto-optik epi li itilize pou wafer sifas acoustic (SAW) ak modulateur AO. CASTECH bay kristal acoustic (SAW) LiNbO3 nan wafers, boule tankou koupe, konpozan fini ak eleman fabrike koutim.
