LiNbO3 Crystal
LiNbO3 (Lithium Niobate) galasi ndi zinthu zambiri zogwiritsa ntchito piezoelectric, Ferroelectric, pyroelectric, nonlinear, Electro-Optical, chithunzielastic, etc. LiNbO3 ili ndi bata yamafuta ndi kupangika kwamakanizo.
Monga imodzi mwazida zodziwika bwino kwambiri zopanga mawonekedwe a Liline, LiNbO3 ndi yoyenera mitundu yosiyanasiyana yosinthira mafayilo. Mwachitsanzo, imagwiritsidwa ntchito kwambiri ngati ma frequency frequency a wavelength> 1 μm ndi ma Optical parametric oscillators (OPOs) opaka 1064 nm komanso zida za quasi-phase-matched (QPM). Chifukwa cha coefficients yawo yayikulu ya EO ndi AO, LiNbO3 Crystal imagwiritsidwanso ntchito ngati gawo modulators, waveguide substrate, pamwamba acoustic wave wafers, ndi Q-switching ya Nd: YAG, Nd: YLF ndi Ti-Sapphire lasers.
LiNbO3 mutha kuyikidwapo ndi zinthu zosiyanasiyana, monga Er, Pr, Mg, Fe, ndi zina zambiri, zomwe zimapatsa zinthu zake zinthu zapadera. Mwachitsanzo, cholowera chowonongeka cha MgO: LiNbO3 ndichoposera chiwiri kuposa cha LiNbO3.
Lumikizanani nafe kuti mupeze yankho lanu labwino la LiNbO3 makhiristo.

Ubwino wa MgO: LiNbO3 poyerekeza ndi LiNbO3
• Kuchita kwapamwamba kwambiri kwapawiri (SHG) kwa pulsed Nd: YAG (65%) ndi CW Nd: YAG (45%)
• Kugwiritsa ntchito kwapamwamba pakugwiritsa ntchito OPO, OPA, QPM zowonjezera ndi waveguide yolumikizidwa
• Zowonongeka kwambiri zowononga patelefoni
Mapulogalamu Oyambirira - LiNbO3
