BBO kristalo

BBO ndi kristalo watsopano wa ultraviole wowirikiza kawiri. Ndi uniaxial kristalo woipa, wokhala ndi index yowoneka bwino (ayi) yokulirapo kuposa index yodabwitsa ya refractive index (ne).Kufananiza kwa gawo la I ndi mtundu wa II kumatha kufikidwa ndi kuwongolera ngodya.
BBO ndi kristalo wothandiza wa NLO wam'badwo wachiwiri, wachitatu ndi wachinayi wamtundu wa Nd: YAG lasers, komanso kristalo wabwino kwambiri wa NLO wam'badwo wachisanu wa harmonic pa 213nm.Kutembenuka kwamphamvu kopitilira 70% kwa SHG, 60% kwa THG ndi 50% kwa 4HG, ndi 200 mW kutulutsa pa 213 nm (5HG) kwapezedwa, motsatana.
BBO imakhalanso kristalo yothandiza pa intracavity SHG yamphamvu kwambiri Nd: YAG lasers.Kwa intracavity SHG ya acousto-optic Q-switched Nd:YAG laser, mphamvu yopitilira 15 W avareji pa 532 nm idapangidwa ndi kristalo wokutidwa ndi AR wa BBO.Ikapopedwa ndi 600 mW SHG kutulutsa kwa mode-locked Nd: YLF laser, 66 mW kutulutsa pa 263 nm idapangidwa kuchokera ku Brewster-angle-cut BBO muzitsulo zakunja zokongoletsedwa.
BBO ingagwiritsidwenso ntchito pa ntchito za EO. Maselo a BBO Pockels kapena EO Q-Switches amagwiritsidwa ntchito kusintha polarization state ya kuwala kudutsamo pamene magetsi akugwiritsidwa ntchito ku electrodes ya electro-optic crystals monga BBO.Beta-Barium Borate ( β-BaB2O4, BBO) yokhala ndi zilembo zowonekera bwino komanso magawo ofananira magawo, ma coefficient akuluakulu osagwirizana, kuwonongeka kwakukulu komanso mawonekedwe abwino kwambiri a optical homogeneity ndi ma electro-optical properties amapereka mwayi wowoneka bwino kwa mitundu yosiyanasiyana ya optical optical and electro-optic applications.
Makhalidwe a BBO Crystals:
• Broad gawo matchable range from 409.6 nm to 3500 nm;
• Dera lofalikira kuchokera ku 190 nm mpaka 3500 nm;
• Chigawo chachikulu chogwira ntchito chachiwiri chaharmonic-generation (SHG) pafupifupi nthawi 6 kuposa kristalo wa KDP;
• Kuwonongeka kwakukulu;
• Homogeneity yapamwamba ya kuwala ndi δn ≈10-6 / cm;
• Kutentha kwakukulu kwa bandwidth pafupifupi 55 ℃.
Chidziwitso chofunikira:
BBO ili ndi chiwopsezo chochepa cha chinyezi.Ogwiritsa ntchito amalangizidwa kuti apereke mikhalidwe yowuma kuti agwiritse ntchito komanso kusunga BBO.
BBO ndi yofewa ndipo imafuna kusamala kuti iteteze malo ake opukutidwa.
Pakafunika kusintha ma angle, chonde dziwani kuti kuvomereza kwa BBO ndikochepa.
