BBO yog ib qho tshiab ultraviole zaus ob npaug siv lead ua.Nws yog ib qho tsis zoo uniaxial siv lead ua, nrog zoo tib yam refractive index (tsis yog) loj dua txawv txawv refractive index (ne).Ob hom I thiab hom II theem sib txuam tuaj yeem ncav cuag los ntawm lub kaum sab xis.
BBO yog ib qho zoo NLO siv lead ua rau lub thib ob, peb thiab thib plaub harmonic tiam ntawm Nd:YAG lasers, thiab qhov zoo tshaj plaws NLO siv lead ua rau lub thib tsib harmonic tiam ntawm 213nm.Kev hloov pauv tau zoo ntawm ntau dua 70% rau SHG, 60% rau THG thiab 50% rau 4HG, thiab 200 mW tso zis ntawm 213 nm (5HG) tau txais, feem.
BBO kuj yog ib qho zoo siv lead ua rau lub intracavity SHG ntawm lub zog siab Nd:YAG lasers.Rau qhov intracavity SHG ntawm acousto-optic Q-hloov Nd:YAG laser, ntau tshaj 15 W nruab nrab lub zog ntawm 532 nm tau tsim los ntawm AR-coated BBO siv lead ua.Thaum nws yog pumped los ntawm 600 mW SHG tso zis ntawm ib hom-xauv Nd: YLF laser, 66 mW tso zis ntawm 263 nm yog tsim los ntawm ib tug Brewster-lub kaum sab xis-txiav BBO nyob rau hauv ib tug sab nraud enhanced resonant kab noj hniav.
BBO kuj tseem siv tau rau EO daim ntawv thov.BBO Pockels hlwb lossis EO Q-Switches yog siv los hloov lub xeev polarization ntawm lub teeb hla nws thaum muaj hluav taws xob siv rau electrodes ntawm electro-optic crystals xws li BBO.Beta-Barium Borate ( β-BaB2O4, BBO ) nrog cov cwj pwm dav dav thiab cov theem sib txuam, cov coefficient loj tsis zoo, qhov kev puas tsuaj siab thiab zoo heev optical homogeneity thiab electro-optical zog muaj peev xwm txaus nyiam rau ntau yam kev siv kho qhov muag thiab cov ntawv siv hluav taws xob.
Nta ntawm BBO Crystals:
• Kev sib tw dav dav ntawm 409.6 nm txog 3500 nm;
• Kev sib kis thoob plaws cheeb tsam ntawm 190 nm txog 3500 nm;
• Loj ua tau zoo thib ob-harmonic-generation (SHG) coefficient txog 6 npaug ntau dua li ntawm KDP siv lead ua;
• Muaj kev puas tsuaj loj;
• High optical homogeneity nrog δn ≈10-6/cm;
• Dav kub-bandwidth ntawm li 55 ℃.
Daim ntawv ceeb toom tseem ceeb:
BBO muaj qhov tsis zoo rau cov dej noo.Cov neeg siv tau qhia kom muab cov kev mob qhuav rau ob qho tib si thov thiab khaws cia ntawm BBO.
BBO kuj yog mos thiab yog li yuav tsum tau ceev faj tiv thaiv nws cov polished nto.
Thaum kho lub kaum sab xis yog tsim nyog, thov nco ntsoov tias lub kaum sab xis txais ntawm BBO yog me me.
