BBO Crystal
BBO (ẞ-BaB2O4) yog cov siv lead ua tsis zoo tshaj plaws nrog kev sib txuas ntawm ntau tus naj npawb ntawm cov yam ntxwv tshwj xeeb: dav hauv cheeb tsam pob tshab, qhov dav theem ntawm qhov sib txuam, cov kab hluav taws xob tsis sib txuas ntawm cov khoom loj, kev puas tsuaj ntau, thiab qhov cuam tshuam zoo tshaj plaws homogeneity. Yog li ntawd, BBO muab txoj kev daws teeb meem zoo rau ntau cov ntawv thov kev kho qhov muag xws li OPA, OPCPA, OPO thiab lwm yam.
BBO tseem muaj qhov zoo ntawm qhov loj thermal txais yuav bandwidth, siab puas tsuaj thiab qhov nqus me me, yog li tsim nyog rau zaus hloov dua siab ntawm qhov siab kawg lossis nruab nrab lub zog laser hluav taws xob, piv txwv li harmonic tiam ntawm Nd: YAG, Ti: Sapphire thiab Alexandrite laser hluav taws xob. BBO yog qhov zoo tshaj plaws NLO siv lead ua rau lub koob thib 5 tiam harmonic ntawm Nd: YAG laser ntawm 213 nm. Cov qib zoo laser nqaj zoo (me me kev sib cais, cov hom mob zoo, thiab lwm yam) yog tus yuam sij rau BBO kom tau txais kev hloov dua siab tshiab.
Tsis tas li, cov kab loj loj kis tau raws li cov sib txuam theem, tshwj xeeb tshaj yog nyob rau hauv UV ntau, ua rau BBO txig haum rau zaus ob zaug ntawm Dye, Argon ion thiab Copper vapor laser hluav taws xob. Ob Hom 1 (oo-e) thiab Hom 2 (eo-e) theem-sib piv cov ces kaum tuaj yeem tau txais, nce tus naj npawb ntawm qhov zoo rau cov ntawv thov sib txawv ntawm BBO.
Tiv tauj peb rau qhov kev daws teeb meem zoo tshaj plaws rau koj daim ntawv thov ntawm BBO muaju.
