LiNbO3 Crystal
LiNbO3 (Lithium Niobate) kristalo chinhu chakawandisa chinobatanidza zvinhu zve piezoelectric, ferroelectric, pyroelectric, nonlinear, electro-Optical, Photoelastic, nezvimwe. LiNbO3 ine yakanaka yekupisa kugadzikana uye kugadzikana kwemakemikari.
Seimwe yezvakanyatsoratidzwa zvisiri zvemahara maziso, LiNbO3 inokodzera akasiyana siyana frequency kutendeuka zvinoshandiswa. Semuenzaniso, inoshandiswa zvakanyanya se frequency frequency yeiyo wavelength> 1 μm uye optical parametric oscillators (OPOs) yakaomeswa pa1064 nm pamwe nemagetsi equasi-phase-matched (QPM). Nekuda kweiyo huru EO uye AO coefficients, LiNbO3 Crystal inowanzoshandiswa kune phase modulators, waveguide substrate, pamusoro acoustic wave wafers, uye Q-switching yeNd: YAG, Nd: YLF uye Ti-Sapphire lasers.
LiNbO3 inogona kuvezwa nezvinhu zvakasiyana, seEr, Pr, Mg, Fe, nezvimwe, izvo zvinopa izvo zvakasarudzika zvivakwa. Semuenzaniso, iyo yekukuvadza chikumbaridzo cheMMO: LiNbO3 inodarika yakapetwa kairi yeiyo yakachena LiNbO3.
Bata isu kune mhinduro yakanakisa yekushandisa kwako kweLiNbO3 makristasi.
