Pab Pawg Tshawb Fawb Island ua qhov kev nce qib tshiab hauv kev sib xyaw ua ke Nd:YAG Thiab Nd:GdYAG Crystal Kev Npaj Thiab Kev Tshawb Fawb Laser

Tsis ntev los no, tus kws tshawb fawb Zhang Qingli pab pawg ntawm Anguang Institute of Hefei Institute of Materials, Suav Academy ntawm Kev Tshawb Fawb thiab tus kws tshawb fawb Jiang Haihe pab pawg ntawm Health Institute ntawm Suav Academy ntawm Kev Tshawb Fawb tau koom tes ntxiv hauv kev tshawb fawb ntawm gradient concentration laser siv lead ua kev loj hlob thiab laser kev ua tau zoo, thiab muaj. zus Nd: YAG thiab Nd: GdYAG laser crystals nrog ntau gradient concentrations los ntawm kev siv vesicle-zoo li txoj kev, thiab Nd: GdYAG laser kev ua tau zoo dua li qhov kwv yees gradient concentration Nd: YAG siv lead ua, thiab cov txiaj ntsig tshawb fawb tau luam tawm hauv " Gradient concentration laser siv lead ua kev loj hlob ". Nd: GdYAG muaj laser kev ua tau zoo dua Nd:YAG nrog kwv yees gradient concentration, thiab cov kev tshawb fawb muaj feem xyuam tau luam tawm nyob rau hauv Optics thiab Laser Technology, ib tug thoob ntiaj teb renowned optics TOP phau ntawv journal, nyob rau hauv lub npe ntawm "Kev loj hlob thiab Laser Performance ntawm Nd:YAG Series Crystals nrog Gradient Concentration".
Lub luminescence kev ua tau zoo ntawm activated ions nyob rau hauv laser muaju yog feem ntau cuam tshuam los ntawm tej yam xws li ligands thiab siv lead ua teb nyob rau hauv matrix crystals. Lub zog theem qauv ntawm gadolinium ions (Gd {{0}}}) yog qhov yooj yim, thiab tsis muaj qhov sib tshooj ntawm lub zog ntawm 4F 3/2, 4I 15/2, 4I 13/2, thiab 4I 11/2 nrog cov neodymium ions (Nd 3+), yog li ntawd tsis muaj kev sib tw ntawm cov qib zog thiab tsis muaj kev nqus yuav raug tsim, thiab kev ua haujlwm luminescence ntawm cov muaju tuaj yeem paub thiab tswj tau. Pab neeg tshawb fawb doped Gd 3+ rau hauv Nd:YAG crystals nrog gradient concentration los ua kom zoo dua qhov kev ua tau zoo ntawm luminescence, thiab siv txoj kev loj hlob vesicular kom loj hlob Nd:YAG thiab Nd:GdYAG laser muaju nrog sib txawv gradient concentrations. Cov concentrations ntawm Nd:YAG thiab Nd:GdYAG yog 0.17-0.38 ntawm% thiab 0. %, thiab cov concentrations ntawm Nd:GdYAG yog 0. Kev nqus coefficients ntawm 808 nm qhia qhov sib txawv ntawm ntau txoj haujlwm raws li kev loj hlob siv lead ua, uas qhia ntxiv tias Nd 3+ concentration hauv cov muaju muaj qhov sib faib gradient. A 3 40 hli laser bar tau raug tshem tawm los ntawm qhov sib npaug ntawm txoj kab uas hla ntawm peb lub ntsej muag, sib npaug thiab lub ntsej muag kawg, ua kom sov lub dab dej tsim thiab ua tiav, lub ntsej muag kawg pumped, nrog rau qhov qis-concentration kawg raws li qhov xwm txheej kawg thiab cov kab noj hniav tiaj tus qauv, thiab cov kev ntsuam xyuas laser tau ua tiav. 0.17-0.38 ntawm % Nd:YAG thiab 0. }%, thiab lub zog tso zis ntau tshaj yog 0.17-0.38 ntawm% thiab 0.18-0.32 ntawm% Nd:GdYAG, raws Lub laser slant efficiency ntawm 0. tseem ceeb.
Cov txiaj ntsig kev sim qhia tau hais tias cov gradient concentration siv lead ua tuaj yeem txhim kho lub laser tso zis efficiency, thiab laser kev ua tau zoo ntawm gradient concentration Nd: GdYAG zoo dua li qhov kwv yees gradient concentration Nd: YAG siv lead ua, thiab gradient concentration laser siv lead ua yuav tsum. muab ib yam tshiab ntawm crystalline cov ntaub ntawv hauv paus rau high-efficiency laser technology.
Txoj haujlwm tshawb fawb no tau txais kev txhawb nqa los ntawm National Natural Science Foundation ntawm Tuam Tshoj (NSFC) thiab Suav Academy ntawm Kev Tshawb Fawb (CAS) Pawg Neeg Saib Xyuas Kev Txhim Kho Cov Hluas.
