Dab tsi yog laser nce nruab nrab?
Ib lub laser nce nruab nrab yog cov khoom siv uas ua kom pom teeb ntsig los ntawm kev tso tawm kev txhawb nqa. Thaum nruab nrab ntawm cov atoms lossis cov lwg me me yog zoo siab rau cov zog siab dua, lawv tuaj yeem emit lub photons ntawm ib lub xeev qis dua. Cov txheej txheem no ua kom sov lub teeb dhau ntawm qhov nruab nrab, uas yog qhov tseem ceeb rau kev lag luam laser.

Dab tsi yog qhov ib txwm muaj nruab nrab?
Qhov nce hauv nruab nrab tuaj yeem sib txawv, suav nrogroj, kua (dyes), cov khib nyiab(Muaju lossis tsom iav doped nrog lub ntiaj teb tsawg lossis hloov cov hlau ions), thiab semiconductors.Khoom-Lub Xeev Lasers, piv txwv li, feem ntau siv cov muaju xws li ND: YAG (neodymium-doped yttrium aluminium garnet nrog tsis tshua muaj kev tsis tshua muaj lub ntiaj teb. Zas lasers siv cov organic dyes yaj nyob rau hauv cov kuab tshuaj, thiab roj roj nkev siv cov roj av lossis roj sib tov.
Laser pas nrig (los ntawm sab laug mus rau sab xis): alexandrite, er: yag, nd: yag
The differences between Nd (Neodymium), Er (Erbium), and Yb (Ytterbium) as gain mediums
Feem ntau cuam tshuam nrog lawv cov khoom siv emissionth, thiab cov kev siv hluav taws xob, tshwj xeeb tshaj yog nyob rau hauv cov ntsiab lus ntawm doped cov ntaub ntawv laser.
Emission yoj:
- ER: Erbium feem ntau emits ntawm 1.55 μm, uas yog qhov muaj txiaj ntsig zoo ntawm cov ntawv thov kev sib tham tau vim nws qhov kev poob qis hauv qhov muag roj (Gong ET AL., 2016).
- YB: ytterbium feem ntau emits nyob ib ncig ntawm 1.0 txog 1.1 μm, ua rau nws muaj kev haum rau ntau cov ntawv thov, suav nrog highers highers highers thiab ampliffiers. YB feem ntau siv los ua cov rhiab rau er kom txhim kho kev ua haujlwm ntawm cov khoom siv er-doped los ntawm yb rau er.
- ND: Neodymium-doped cov ntaub ntawv feem ntau tshwm sim ib puag ncig 1.06 μm. ND: YAG, piv txwv li, muaj npe rau nws txoj kev ua tau zoo thiab yog siv dav hauv ob qho tib si kev lag luam thiab kho mob li al., 2009).
Zog Hloov Cov Mechanisms:
- ER thiab YB co-doping: txoj kev sib koom ua ke ntawm ER thiab YB nyob rau hauv tus tswv hauv nruab nrab tau txais txiaj ntsig rau kev txhim kho cov emissionicial lub tswv yim hauv 1.5-1.6 μm. YB ua raws li cov khoom siv tau zoo rau er los ntawm nqus twj tso kua mis thiab hloov lub zog los ua kom nrov emission hauv kev sib tham hauv xov tooj. Qhov hloov hluav taws xob no yog qhov tseem ceeb rau kev ua haujlwm ntawm er-doped fiber ntau ampliffiers (EDFA) (DK Vysokikh li al., 2023).
- ND: ND tsis yog feem ntau yuav tsum tau muaj kev xav zoo li YB hauv er-doped systems. Nd ua tau zoo tau muab los ntawm nws qhov ncaj qha ntawm nws cov khoom tawg ntawm lub teeb thiab emission, ua rau nws ncaj thiab txuag nyiaj laser nce nruab nrab.
Cov Ntawv Thov:
- ER:Feem ntau siv hauv kev sib txuas lus vim nws qhov kev tso tawm ntawm 1.55 μm, uas sib xyaws nrog qhov kawg ntawm cov khoom poob ntawm siterical fibers. ER-doped nce cov nruab nrab yog qhov tseem ceeb rau kev kho kom zoo nkauj thiab lasers hauv kev sib txuas lus ntev fiber ntau cov khoom sib txuas lus ntev.
- YB:Feem ntau siv nyob rau hauv cov ntaub ntawv muaj zog siab vim nws cov qauv hluav taws xob yooj yim uas tso cai rau kev ua haujlwm zoo thiab muaj zog tso zis. YB-doped cov ntaub ntawv kuj tau siv los txhim kho kev ua tau zoo ntawm ir-doped systems.
- ND: Zoo-haum rau ntau cov ntawv thov, los ntawm kev ua lag luam txiav thiab vuam rau lasers kho mob. ND: YAG lasers tau tshwj xeeb tshwj xeeb rau lawv txoj kev txuag, lub zog, thiab versatility.
Vim li cas peb ho xaiv ND: YAG li qhov nce nruab nrab hauv DPSs laser
DPSs laser yog ib hom laser uas siv lub teeb tsa-lub xeev tau txais nruab nrab (zoo li ND: YAG) TAG NRHO LASERNIVE LASER DIODE. Cov thev naus laus zis no tso cai rau kev cog lus, muaj txiaj ntsig zoo los ua cov kab teeb zoo hauv qhov pom-rau-infrared spectrum. Rau cov ncauj lus kom ntxaws, koj yuav txiav txim siab tshawb nrhiav los ntawm cov ntaub ntawv sau npe nrov los yog cov tshaj tawm rau kev txheeb xyuas cov thev naus laus zis laser.
[Cov Khoom Uas Lwm Yam:Diode-compor-State laser]
ND: YAG feem ntau siv raws li qhov nruab nrab hauv semiconductor-nqus laser modules rau ntau yam, raws li tau hais los ntawm ntau yam kev tshawb fawb:
1.High efficiency thiab lub zog tawm: Tus qauv tsim thiab sim raws ntawm Diode sab-pumped ND: YAG Laser muab tso ua ke rau ib qho nruab nrab ntawm mem tes hauv ntau cov mem tes hauv ntau qhov chaw ntau. Qhov no qhia tau qhov ua tau zoo thiab muaj peev xwm rau cov zog hluav taws xob tawm ntawm ND: YAG lasers thaum nqus dej los ntawm diodes (Lera li al., 2016).
2. Lub plawv thiab kev ntseeg tau: ND: Yag ceramics tau pom tias muaj txiaj ntsig ntawm ntau qhov muag wavelength, nrog high kho qhov muag-rau-optical efficiency. Qhov no qhia pom ND: YAG cov versatility thiab kev ntseeg tau raws li qhov nce nruab nrab hauv cov ntawv thov Laser sib txawv (Zhang li al., 2013).
3.MONEVITY THIAB BOOB ZOO: Kev tshawb fawb ntawm qhov ua tau zoo, ND: YAG laser paub txog kev ua haujlwm ntev thiab ua tau zoo ib yam rau cov ntawv thov kom tas li thiab txhim khu kev qha. Txoj kev tshawb no tau tshaj tawm cov haujlwm txuas ntxiv nrog ntau dua 4.8 x 10 ^ 9 txhaj tshuaj yam tsis muaj kev puas tsuaj zoo (tswj cov nqaj zoo (suav txog al., 2004).
4.Highly qhov kev ua lag luam-nthwv dej:Cov kev tshawb fawb tau pom qhov ua tau zoo tas li-nthwv dej (CNE) Qhov no suav nrog kev hloov kho siab rau siab thiab cov kab nqes hav, txuas ntxiv ua raws li kev haum ntawm ND: YAG rau cov ntawv thov Higher ua haujlwm (ZHU li al., 2013).
Kev sib xyaw ua ke ntawm kev ua haujlwm siab, kev tawm tsam hluav taws xob, kev tiv thaiv kev ua haujlwm, ntev thiab cov khoom siv Laser Laser rau ntau cov ntawv thov.
