LiNbO3 Crystal
LiNbO3 (Lithium Niobate) crystal waa maaddooyin badan oo isku-dhafan oo isku-darka guryaha ku habboon ee loo yaqaan 'pezoelectric, ferroelectric, pyroelectric, nonlinear, electro-optical, photoelastic, iwm' 'LiNbO3 waxay leedahay degenaansho kuleylka iyo deganaanshaha kiimikada.
Sida mid ka mid ah alaabada indhaha ee aan tooska ahayn ee lagu garto, LiNbO3 wuxuu ku habboon yahay codsiyo kala-beddelasho oo kala-duwan. Tusaale ahaan, waxaa si balaadhan loogu isticmaalaa laba laablaabyada mowjadaha> 1 μm iyo qalabka loo yaqaan 'optical parametric oscillators (OPOs)' oo la bamgareeyay 1064 nm iyo sidoo kale aaladaha wejiga-u-dhigma (QPM). Isku xidhka weyn ee EO iyo AO, LiNbO3 crystal waxaa sidoo kale caadi ahaan loo isticmaalaa qalabka wajiga lagu beddelo, mitirka mawjadaha, wareejinta dusha sare ee acoustic, iyo Q-wareejinta ee Nd: YAG, Nd: YLF iyo lasers-ka-Sapphire.
LiNbO3 waxaa lagu daaweyn karaa waxyaabo kala duwan, sida Er, Pr, Mg, Fe, iwm., kuwaas oo siiya sheyga guryaha u gaarka ah. Tusaale ahaan, bilowga waxyeellada ee MgO: LiNbO3 wuu ka badan yahay labanlaab ka mid ah 'LiNbO saafi ah'3.
Nagala soo xiriir xalka ugu fiican ee dalabkaaga ee LiNbO3 kiristaalo.
