LiNbO3 Makristasi


Chigadzirwa Chigadzirwa

Vhidhiyo

LiNbO3 Crystal ine yakasarudzika electro-optical, piezoelectric, photoelastic uye nonlinear optical zvivakwa. Iwo akasimba birefringent. Iwo anoshandiswa mu laserfrequency kuwedzerana, nonlinear optics, Pockels maseru, oparical parametric oscillators, Q-switching zvishandiso zve lasers, mamwe acousto-opticdevices, Optical switch for gigahertz frequency, nezvimwewo. 
Kazhinji LiNbO3 wafer inoiswa indexed seX yakatemwa, Y yakatemwa kana Z yakatemwa ine trigonal mamiriro, zvakare inogona kuverengerwa nehexagonal mamiriro. Shanduko kubva ku trigonal -index system kuenda kune hexagonal se [u 'v' w '] ---> [uvtw] kunoitwa neanotevera mafomula:
X-cut (110) = (11-20) kana (22-40) XRD 2theta iri 36.56 kana 77.73 degrees
Y-cheka (010) = (10-10), (20-20) kana (30-30) XRD 2theta iri 20.86,42.46,65.83 madhigirii.
LiNbO3 uye MgO: LN Pockels Cell ine yakakwira kutapurirana muhupamhi hwakawanda wavelength renji kubva 420 - 5200 nm. MgO: LiNbO3 EO Crystal ine yakafanana electro-optic zvivakwa kuLiNbO3 Crystal asi ine yakanyanya kukuvara chikumbaridzo. Nezve MgO: LN Crystal, iyo refractive index yeiyo optical medium inoshandurwa nekuvapo kwenzwi, izvi zvinodaidzwa acousto-optic athari iyo inogona kushandiswa mune akawanda madhijitori anosanganisira optical modulators, q switch, deflectors, mafirita, frequency shifters uye spectrum. vaongorori. LN EO Q-chinja uye MgO: LN EO Q-Chinja chakagadzirwa neCoupletech ine kuvimbika kwakakwirira uye kwakanyanya kushandurwa.
