LiNbO3 Crystal
LiNbO3 (Lithium Niobate) gara jẹ ohun elo onisẹpọ ti o ṣepọ awọn ohun-ini ti pinzoelectric, ferroelectric, pyroelectric, nonlinear, electro-optical, photoelastic, bbl LiNbO3 ni iduroṣinṣin gbona ti o dara ati iduroṣinṣin kemikali.
Gẹgẹbi ọkan ninu awọn ohun elo opini ti kii ṣe deede ti ko dara, LiNbO3 dara fun ọpọlọpọ awọn ohun elo iyipada igbohunsafẹfẹ. Fun apẹẹrẹ, o gbajumo ni lilo gẹgẹ bi ilọpo meji fun igbi-ije> 1 μm ati oscillators opitika (OPOs) opitika ni 1064 nm bakanna pẹlu awọn ẹrọ fifẹ-ni-baamu (QPM). Nitori ti awọn alajọpọ EO ati AO awọn iṣọpọ, LiNbO3 gara jẹ tun lo wọpọ fun awọn oludari alakoso, aropo-wiwọn igigirisẹ, awọn ohun elo igbi omi awọ, ati awọn iyipo Q-yipada ti Nd: YAG, Nd: YLF ati awọn okun-oniyebiye Sapphire.
LiNbO3 le ṣe pẹlu ọpọlọpọ awọn eroja, bii Eri, Pr, Mg, Fe, ati bẹbẹ lọ, eyiti o fun awọn ohun-ini alailẹgbẹ ohun elo naa. Fun apẹẹrẹ, iloro ibaje ti MgO: LiNbO3 ju ilọpo meji lọ ti LiNbO funfun3.
Kan si wa fun ipinnu ti o dara julọ fun ohun elo rẹ ti LiNbO3 awọn kirisita.
