Nd:YVO₄ (Neodymium-doped Yttrium Vanadate) yog lub siab- laser siv lead ua, tshwj xeeb tshaj yog haum raudiode-pumped, low to medium power lasers.
Cov txiaj ntsig tseem ceeb:
1: Absorption efficiency ntawm 808 nm yog hais txog5 × siab duathan Nd:YAG
2: Stimulated emission cross-section ntawm 1064 nm yog hais txog3 × loj
3: Tsawg lasing pib & ntau dua efficiency
4: Ib txwm linearly polarized tso zis
5: Kev hloov pauv tau zoo dua rau LD kub hloov pauv
Daim ntawv thov:
1: Machinery, cov ntaub ntawv ua, spectroscopy, tshuaj ntsuam xyuas, laser luam ntawv, cov ntaub ntawv khaws cia, thiab lwm yam.
2: Compact, npaum, thiab txhim khu kev qha - Nd:YVO₄ yog qhov kev xaiv zoo tshaj plaws rau - tiam diode-pumped laser systems.
Nd:YVO₄ crystalyog cov khoom tsim los ntawm kev ntxiv neodymium ions rau hauv yttrium vanadate. Nws feem ntau yog siv los ua cov khoom siv laser nruab nrab hauv diode-pumped solid-state lasers. Cov siv lead ua zoo li pob tshab xiav - cov khoom siv grey thiab paub txog nwssiab optical nce, zoo thermal conductivity, thiab qis laser pib.
Nd:YVO₄ crystals yog siab - cov ntaub ntawv laser kev ua tau zoo siv dav hauv kev lag luam thiab kev kho mob lasers. Nov yog vim li cas lawv tshwj xeeb:
Muaj zog nqus & ua tau zoo emission- ua haujlwm zoo nrog diode twj, nrog emission peaks ntawm 1064 nm thiab 1342 nm.
High thermal conductivity- dissipates tshav kub zoo, zoo meej rau siab - zog ua haujlwm.
Nonlinear optics npaj- Txhawb nqa zaus ob npaug thiab sib tov, zoo tagnrho rau tsim ntsuab lossis lwm yam wavelengths.
Durable- kev puas tsuaj siab ua kom muaj kev ntseeg siab nyob rau hauv lub teeb laser hnyav.
Compact & ntau yam- haum rau ntau lub tshuab laser thiab kev siv.
Hauv luv luv, Nd:YVO₄ yog qhov kev xaiv txhim khu kev qha rau txhua tus neeg tab tom nrhiav tsimua tau zoo, siab -kev ua haujlwm laser tshuab.
Ib hom tshiab ntawm neodymium-doped yttrium vanadate (Nd:YVO₄) siv lead ua.
Doping concentration yog 3%. Cov ntsej muag siv lead ua yog polished rau dav hlau- cov chaw sib luag thiab tsis muaj coated.
Crystal loj: 3 x 3.3 x 12 mm.
Lub luag haujlwm tseem ceeb ntawm 3x3x3mm Nd: YVO4 siv lead ua yog qhov siab -kev ua tau zoo laser nce nruab nrab rau kev tsim cov compact, siab -efficiency solid- xeev lasers, tshwj xeeb tshaj yog haum rau semiconductor twj. Nws cov txiaj ntsig muaj xws li kev nqus dej siab coefficient, siab zog emission hla ntu, kev nqus bandwidth dav, thiab muaj peev xwm los tawm cov teeb pom kev zoo. Qhov me me ntawm Nd: YVO4 siv lead ua ua rau cov khoom siv laser me me uas muaj peev xwm tsim tau ntau yam laser wavelengths, suav nrog ntsuab, xiav, thiab liab.
