3inch 4 nti 6inch LiNbO3 Wafer Substrate Ib leeg siv lead ua khoom
Cov ncauj lus kom ntxaws
Lithium niobate crystals muaj zoo heev electro-optic, acoustooptic, piezoelectric thiab nonlinear zog. Lithium niobate siv lead ua yog ib qho tseem ceeb multifunctional siv lead ua nrog zoo nonlinear optical zog thiab loj nonlinear optical coefficient. Tsis tas li ntawd, kev sib piv tsis tseem ceeb ntawm theem tuaj yeem pom tau. Raws li electro-optical siv lead ua, nws tau siv los ua ib qho tseem ceeb ntawm cov khoom siv kho qhov muag. Raws li piezoelectric siv lead ua, nws tuaj yeem siv rau hauv kev tsim cov lim dej tsawg zaus SAW, lub zog siab siab kub resistant ultrasonic transducers thiab lwm yam. Doped lithium niobate cov ntaub ntawv kuj tau siv dav. Mg: LN tuaj yeem txhim kho qhov kev tiv thaiv kev puas tsuaj rau laser, thiab txhawb kev siv cov lithium niobate crystals hauv thaj tsam ntawm cov khoom siv tsis zoo. Nd: Mg: LN siv lead ua, tuaj yeem ua tiav nws tus kheej ob npaug; Fe: LN crystals tuaj yeem siv rau holographic cia hauv qhov muag ntim.
