    Vhidhiyo

    BBO iyi nyowani ultraviole frequency inopetwa sekristaro Iyo isina kunaka uniaxial kristaro, ine yakajairika refractive index (kwete) yakakura kupfuura inoshamisa refractive index (ne). Ose ari maviri mhando I uye mhando II chikamu chinowirirana chinogona kusvikwa ne angle tuning. 
    BBO inoyevedza NLO kristaro yechizvarwa chechipiri, chechitatu uye chechina chinowirirana cheNd: YAG lasers, uye yakanakisa NLO kristaro yechizvarwa chechishanu cheharmonic pa213nm. Kutendeuka kushanda kweanopfuura 70% kweSHG, 60% ye THG uye 50% ye4HG, uye 200 mW kuburitsa pa213 nm (5HG) yakawanikwa, zvichiteerana.
    BBO zvakare inoenderana nekristaro yeiyo yekusavanzika SHG yemasimba makuru Nd: YAG lasers. Kune kusanzwisisika SHG yeacousto-optic Q-yakachinjika Nd: YAG laser, inopfuura 15 W avhareji simba pa532 nm yakagadzirwa neAAR-yakavharwa BBO kristal. Kana ichinge yapombwa neiyo 600 mW SHG kuburitsa ye-mode-yakavharwa Nd: YLF laser, 66 mW kuburitsa pa263 nm yakagadzirwa kubva kuBrewster-angle-cut-BBO mune yekunze yakasimbiswa resonant mhango.
    BBO inogona zvakare kushandiswa kune EO mashandisirwo. BBO Pockels maseru kana EO Q-Swichi anoshandiswa kushandura iyo polarization nyika yechiedza ichipfuura napo kana magetsi achiiswa kune maelektrode emagetsi emagetsi-akadai seBBO. Beta-Barium Borate (β-BaB2O4, BBO) ine macustomer akajeka kujekesa uye zvikamu zvinowirirana zvikamu, yakakura nonlinear coefficient, yakanyanya kukuvara chikumbaridzo uye yakanakisa Optical homogeneity uye electro-Optical zvivakwa zvinopa zvinokwezva mikana yezvakasiyana nonlinear Optical application uye electro-optic zvinoshandiswa.
    Zvimiro zveBBO Makristasi:
    Chikamu chakakura chinowirirana kubva pa409.6 nm kusvika 3500 nm;
    Dunhu rakakura rekutakura kubva ku190 nm kusvika 3500 nm;
    • Yakakura inoshanda yechipiri-harmonic-chizvarwa (SHG) coefficient kanokwana ka6 kakakura kupfuura iyo yeKDP kristaro;
    • Kukwirira kwakanyanya chikumbaridzo;
    • Yakakwira Optical homogeneity ne δn ≈10-6 / cm;
    Wide tembiricha-bandwidth ingangoita 55 ℃.
    Chiziviso chakakosha:
    BBO ine yakaderera kubata kune iyo mwando. Vashandisi vanorayirwa kuti vape yakaoma mamiriro kune ese mashandisirwo uye kuchengetedzwa kweBBO.
    BBO yakapfava uye nekudaro inoda matanho ekuchengetedza nzvimbo dzayo dzakakwenenzverwa.
    Kana kukona kuchinjika kuchidikanwa, ndapota ramba uchifunga kuti kona yekugashira yeBBO idiki
