LN - Q Yahinduye Crystal

Ibisobanuro bigufi:

LiNbO3 ikoreshwa cyane nka moderi ya electro-optique na Q-switch ya Nd: YAG, Nd: YLF na Ti: Lazeri ya safiro kimwe na modulator ya fibre optique. Imbonerahamwe ikurikira irerekana ibisobanuro bya LiNbO3 isanzwe ikoreshwa nka Q-ihinduranya hamwe na moderi ya EO ihinduka.

Umucyo ukwirakwira muri z-axis kandi amashanyarazi akoreshwa kuri x-axis. Coefficient ya electro-optique ya LiNbO3 ni: r33 = 32 pm / V, r31 = 10 pm / V, r22 = 6.8 pm / V kuri frequency nkeya na r33 = 31 pm / V, r31 = 8.6 pm / V, r22 = 3.4 pm / V kumurongo mwinshi w'amashanyarazi. Igice cya kabiri cyumuvuduko: Vπ = λd / (2no3r22L), rc = (ne / oya) 3r33-r13.LiNbO3 nayo ni kristu nziza ya acousto-optique kandi ikoreshwa mubutaka bwa acoustic (SAW) wafer na moderi ya AO. CASTECH itanga urwego rwa acoustic (SAW) urwego rwa LiNbO3 kristal muri wafer, nkuko byacishijwe bugufi, ibice byarangiye nibintu byahimbwe.
