BBO is a new ultraviole frequency double crystal crystal.Iri negative uniaxial crystal, ine yakajairwa refractive index (kwete) yakakura kudarika extraordinary refractive index (ne).Ose ari maviri mhando I uye mhando II chikamu chekufananidza chinogona kusvikwa nekona tuning.
BBO ikiristaro inoshanda yeNLO yechipiri, yechitatu uye yechina harmonic chizvarwa cheNd: YAG lasers, uye yakanakisa NLO crystal yechizvarwa chechishanu harmonic pa213nm.Shanduko inobudirira inodarika makumi manomwe muzana yeSHG, 60% yeTHG uye 50% ye4HG, uye 200 mW yakabuda pa213 nm (5HG) yakawanikwa, zvichiteerana.
BBO zvakare iri kristaro inoshanda kune intracavity SHG yesimba repamusoro Nd: YAG lasers.Kune intracavity SHG yeacousto-optic Q-switched Nd: YAG laser, anopfuura 15 W avhareji yesimba pa532 nm yakagadzirwa neAR-yakavharwa BBO crystal.Kana ichipombwa ne600 mW SHG yakabuda yemodhi-yakakiiwa Nd:YLF laser, 66 mW yakabuda pa263 nm yakagadzirwa kubva kuBrewster-angle-cut BBO mune yekunze yakagadziridzwa resonant cavity.
BBO inogonawo kushandiswa kuEO applications.BBO Pockels cells kana EO Q-Switches dzinoshandiswa kushandura polarization state yechiedza chinopfuura nepairi kana magetsi aiswa kumaelectrodes eelectro-optic crystals akadai seBBO.Beta-Barium Borate ( β-BaB2O4, BBO) ine mavara akasiyana-siyana akajeka uye mapeji ekufananidza mitsara, yakakura isina mutsara coefficient, yakakwirira kukuvara kwechikumbaridzo uye yakanakisa optical homogeneity uye electro-optical properties zvinopa mikana inoyevedza kune dzakasiyana-siyana dzisina mutsara optical application uye electro-optic application.
Zvinoumba BBO Crystals:
• Broad phase matchable range kubva 409.6 nm kusvika 3500 nm;
• Wide transmission region kubva 190 nm kusvika 3500 nm;
• Yakakura inoshanda yechipiri-harmonic-generation (SHG) coefficient inenge 6 nguva huru kupfuura yeKDP crystal;
• High kukuvadza chikumbaridzo;
• High optical homogeneity ne δn ≈10-6 / cm;
• Wide tembiricha-bandwidth inosvika 55 ℃.
Chiziviso chakakosha:
BBO ine yakaderera susceptibility kune mwando.Vashandisi vanorayirwa kuti vape yakaoma mamiriro ekushandisa uye kuchengetedza kweBBO.
BBO yakapfava saka inoda kungwarira kudzivirira nzvimbo dzayo dzakakwenenzverwa.
Kana kugadziridzwa kwekona kuchidikanwa, ndapota yeuka kuti kona yekugamuchira yeBBO idiki.
