YVO4 Substrate txhais
YVO4 (Yttrium Orthovanadate) substrate yog hais txog cov khoom siv crystalline feem ntau siv hauv ntau yam kev siv kho qhov muag thiab optoelectronic.Nov yog qee cov ntsiab lus tseem ceeb txog YVO4 substrates:
1. Cov qauv siv lead ua: YVO4 muaj cov qauv siv lead ua tetragonal, thiab yttrium, vanadium, thiab oxygen atoms yog teem rau hauv peb-dimensional lattice.Nws belongs rau lub orthorhombic crystal system.
2. Lub teeb kis tau tus mob: YVO4 muaj ntau yam ntawm lub teeb kis tau tus mob, los ntawm ze ntawm ultraviolet (UV) mus rau nruab nrab-infrared (IR) cheeb tsam.Nws tuaj yeem xa lub teeb ntawm kwv yees li 0.4 μm mus rau 5 μm, ua rau nws haum rau ntau hom kev siv kho qhov muag.
3. Birefringence: YVO4 muaj zog birefringence, uas yog, nws muaj qhov sib txawv refractive indices rau txawv polarized teeb.Cov cuab yeej no yog qhov tseem ceeb rau kev siv xws li waveplates thiab cov lim polarizing.
4. Nonlinear optical zog: YVO4 muaj zoo heev nonlinear optical zog.Nws tuaj yeem tsim cov zaus tshiab lossis hloov cov khoom ntawm qhov teeb meem teeb meem los ntawm kev sib cuam tshuam tsis sib xws.Cov cuab yeej no yog siv nyob rau hauv daim ntawv thov xws li zaus ob npaug (thib ob harmonic tiam) ntawm lasers.
5. High Laser Damage Threshold: YVO4 muaj lub siab ntev laser kev puas tsuaj, uas txhais tau hais tias nws tuaj yeem tiv taus cov kab hluav taws xob ntau yam tsis muaj kev puas tsuaj loj lossis degradation.Qhov no ua rau nws haum rau siab zog laser daim ntaub ntawv.
6. Thermodynamic zog: YVO4 muaj qhov zoo thermal stability thiab txhua yam muaj zog, ua kom nws tuaj yeem tiv taus qhov kub thiab txias thiab kev ntxhov siab ntawm txhua yam yam tsis muaj kev cuam tshuam loj lossis tsis zoo.
7. Kev ruaj ntseg tshuaj: YVO4 muaj tshuaj lom neeg ruaj khov thiab tiv taus cov kuab tshuaj thiab cov kua qaub, ua kom nws cov kav ntev thiab kev ntseeg siab nyob rau hauv ntau yam kev ua haujlwm thiab ib puag ncig.
YVO4 substrates tau dav siv hauv kev siv xws li laser tshuab, optical amplifiers, zaus converters, beam splitters, thiab yoj daim hlau.Nws ua ke ntawm optical transparency, birefringence, nonlinear optical zog, siab laser kev puas tsuaj pib, thiab zoo thermal thiab mechanical stability ua rau nws muaj ntau yam khoom siv nyob rau hauv optics thiab optoelectronics.
