Pfupi Ongororo yeLithium Niobate Crystal uye Zvishandiso Zvayo - Chikamu 4: Pedyo-Stoichiometric Lithium Niobate Crystal

Kuenzaniswa nezvakajairika LNkristaro(CLN)nekuumbwa kwakafanana, kushaikwa kwe lithium iri pedyo-stoichiometricLNkristaro(SLN)zvinotungamira kukudzikisira kwakakosha kwekuremara kwelatisi, uye zvivakwa zvakawanda zvinoshanduka zvinoenderana.Tafura inotevera inoronga chikurumisiyano yezvinhu zvemuviri.

Kuenzaniswa neCLNine chimiro chakafanana, mazhinji ezvimiro zveSLNzvakavandudzwa kusvika pamatanho akasiyana.Iyo inonyanya kukosha optimization inosanganisira:

(1) Whether photorefractive doping, anti-photorefractive doping kana laser-activated ion doping,SLN inemore sensitive performance regulation effect.Kong et al.akawana kuti kana [Li]/[Nb] yasvika 0.995 uye magnesium yemukati iri 1.0mol%, iyo photorefractive kuramba kweiyoSLNinogona kusvika 26 MW/cm2, inova 6 maodha ehukuru hwepamusoro kupfuura iyo yeCLNnechimiro chakafanana.Photorefractive doping uye laser-activated ion doping inewo maitiro akafanana.

(2) Sehuwandu hwekuremara kwelatisi mukatiSLNkristaro inodzikira zvakanyanya, ndizvo zvinoitawo kusimba kwemunda wekristaro, uye voltage inodiwa kuti polarization idzore inodzikira kubva pa21 kV/mm.(yeCLN)kusvika ku5 kV/mm, iyo inobatsira zvikuru pakugadzirwa kwemidziyo ye superlattice.Uyezve, iyo yemagetsi domain chimiro cheSLNinowanzoitika uye madziro edura ari nyore.

(3)Mazhinji photoelectriczvimiro zveSLNzvakare akavandudzwa zvakanyanya, senge electro-optic coefficientr61yakawedzera ne63%, nonlinear coefficient yakawedzera ne22%, crystal birefringence yakawedzera ne43% (wavelength 632.8 nm), blue shiftyeUVabsorption edge, nezvimwewo.
