LiNbO3 Crystal
LiNbO3 (Lithium Niobate) kristal abu ne mai yawa wanda ke haɗe da kaddarorin bizoelectric, ferroelectric, pyroelectric, nonlinear, electro-optical, photoelastic, da sauransu LiNbO3 yana da kyakkyawar kwanciyar hankali da kwanciyar hankali na sinadarai.
A matsayin daya daga cikin kayan da ba na zamani ba sosai, LiNbO3 ya dace da yawan aikace-aikacen juyawa da yawa. Misali, ana amfani dashi sau biyu kamar na sau biyu don lewaƙwalwa> 1 μm da pcetiket na otcillators (OPOs) wanda aka tsinkaye a 1064 nm da kuma na'urorin kwatancen-kashi-aya (QPM). Saboda babban coefficients EO da AO, LiNbO3 Hakanan ana amfani da kristal ana amfani da su don injin zamani, rakodin motsin iska, warts na ruwa acoustic, da kuma sauyawar Q-sauyawa na Nd: YAG, Nd: YLF da lasers na Sapphire.
LiNbO3 za a iya doped tare da abubuwa da yawa, irin su Er, Pr, Mg, Fe, da dai sauransu, waɗanda ke ba da kayan ɗabi'un na musamman. Misali, bakin lalacewar MgO: LiNbO3 yafi ninki biyu fiye da na LiNbO3.
Tuntube mu don mafita mafi kyawun aikace-aikacen ku na LiNbO3 lu'ulu'u ne.
