Yini i-laser ukuthola okuphakathi?

I-Laser Get Medium eyi-Medial iyinto ekhuthaza ukukhanya ngokuphuma okuvuselelayo. Lapho ama-athomu noma ama-molecule aphakathi nendawo ajabule ngamazinga aphezulu wamandla, angakhipha ama-poplen ane-wavelength ethile lapho ebuyela esimweni samandla aphansi. Le nqubo ikhulisa ukukhanya okudlula okuphakathi nendawo, okuyisisekelo ekusebenzeni kwe-laser.

Yini inzuzo ejwayelekile ephakathi?

Inzuzo ephakathi ingahlukahluka, kufaka phakathiAmagesi, uketshezi (udayi), ama-solids(amakristalu noma izibuko zidonswe nge-rare-yomhlaba noma i-metal yensimbi), kanye nama-semiconductors.Ama-lasers aqinile wombuso, ngokwesibonelo, kuvame ukusebenzisa amakristalu afana ne-ND: i-yag (neodymium-doped yttrium aluminium garonet) noma izibuko ezihlanjululwe ngezinto ezingajwayelekile. Idayi Lasers isebenzisa amadayi we-organic ancibilikisiwe kuma-solvents, kanye nama-lasers egesi asebenzisa amagesi noma ama-methix.

Izinduku ze-laser (kusuka kwesobunxele kuye kwesokudla): URuby, Alexandrite, Er: Ag, ND: I-Yag

Umehluko phakathi kwe-ND (Neodymium), er (Erbium), ne-YB (Ytterbium) njengabathola abaphakathi

Ngokuyinhloko uhlobana nezikhathi zabo zokuphuma, izindlela zokudlulisa amandla, kanye nezicelo, ikakhulukazi kumongo wezinto zokwakha ze-doped laser.

Imigwaqo Emission:

- I-ER: I-Erbium ngokuvamile ikhipha ku-1.55 μm, esesifundeni esiphephile samehlo futhi ilusizo kakhulu kwizicelo zokuxhumana ngocingo ngenxa yokulahleka kwayo okuphansi ku-Optical Fibers (Gong et al., 2016).

- I-YB: I-YTTERBIUM Imvamisa ihlala izungeze i-1.0 kuya ku-1.1 μm, okwenza ilungele izinhlelo eziningi ze-application, kufaka phakathi ama-lasers anamandla aphezulu kanye nama-amplifiers. I-YB ivame ukusetshenziswa njenge-sensitizer ye-er ukuthuthukisa ukusebenza kahle kwamadivayisi we-er-doped ngokudlulisa amandla kusuka ku-YB kuya ku-YB.

- ND: Izinto ze-neodymium-doped zivame ukukhipha cishe i-1.06 μm. I-ND: Isibonelo, ngokwesibonelo, idume ngokusebenza kahle kwayo futhi isetshenziswa kabanzi kuwo womabili ama-lasers wezimboni nakwezokwelapha (y. Chang et al., 2009).

Izindlela zokudlulisa amandla:

- I-ER ne-YB Cooping: I-co-doping ye-ER ne-YB ku-Homent Medium inenzuzo yokuthuthukisa ukuthuthumela ibanga le-1.5-1.6 μM. I-YB isebenza njenge-sensitizer esebenza kahle nge-ER ngokuthola ukukhanya kwepompo nokudlulisa amandla kuma-er ion, okuholela ekukhishweni okukhulisiwe kwebhendi yezokuxhumana. Lokhu kudluliswa kwamandla kubalulekile ekusebenzeni kwe-er-doped fiber amplifiers (Edfa) (dk vysokikh et al., 2023).

- ND: I-ND ayidingi ngokujwayelekile i-Sensitizer njenge-YB ezinhlelweni ze-ER-DOPED. Ukusebenza kahle kwe-ND kususelwa ekutholweni kwayo okuqondile kokukhanya kwepompo nokukhipha okulandelayo, okwenza kube yinto eqondile futhi esebenza kahle ye-laser ukuthola okuphakathi nendawo.

Izicelo:

- ER:Ngokuyinhloko esetshenziswa ekuxhumaneni ngocingo ngenxa yokuphuma kwayo ku-1.55 μm, okuhambisana newindows elahlekile eliphansi le-Silica Optical Fibers. Abakwa-Er-Doped Gaudiums babucayi kuma-amplifiers ama-optical amplifiers nama-lasers amabanga amade we-fiber optic zokuxhumana.

- YB:Imvamisa esetshenziswa kuzinhlelo zokusebenza zamandla aphezulu ngenxa yesakhiwo sayo se-elekthronikhi esilula esivumela ukupompa okusebenzayo kwe-diode kanye nokukhipha amandla aphezulu. Izinto ze-yb-doped nazo zisetshenziselwa ukuthuthukisa ukusebenza kwezinhlelo ze-ER-DOPED.

- ND: Ilungele kahle izinhlobo ezahlukahlukene zezicelo, kusuka ekusikeni kwezimboni kanye ne-welding kuma-lasers ezokwelapha. I-ND: Ama-Lasers we-YAG abhekwa ikakhulukazi ukusebenza kwawo, amandla, nokuguquguquka okuhlukahlukene.

Kungani sikhethe i-ND: i-yag njenge-inzuzo ephakathi ku-DPSS laser

I-laser ye-DPSS uhlobo lwe-laser olusebenzisa inzuzo eqinile yombuso (njenge-ND: i-yag) epompo yi-semiconductor laser diode. Lobu buchwepheshe buvumela ama-compact, ama-lasers asebenza kahle akwazi ukukhiqiza imishayo esezingeni eliphakeme ku-spectrum ebonakalayo kuya ku-inf-to-infrared. Ukuze uthole i-athikili eningiliziwe, ungahle ucabange ngokusesha ngemininingwane yesayensi edumile noma abashicileli bezibuyekezo eziphelele kubuchwepheshe be-DPSS Laser.

I-ND: I-Yag ivame ukusetshenziswa njengethonya eliphakathi kumamojula we-laser we-semiconductor ngenxa yezizathu eziningana, njengoba kuqokonyiswe izifundo ezahlukahlukene:

Ukusebenza kahle kwe-1.High kanye nokukhipha amandla: Idizayini kanye nokumbumbuluzwa kwe-nd ye-diode eseceleni Lokhu kukhombisa ukusebenza kahle kakhulu kanye nokungenzeka kokukhishwa kwamandla okuphezulu kwe-ND: Ama-Lag Lasers lapho kuphobhozwa yiDiodes (Lera et al., 2016).
Ukuvumelana nezimo kanye nokwethenjwa: ND: I-Ceramics Yag iboniswe ukusebenza kahle emagabeleni ahlukahlukene, kufaka phakathi ama-wavelength aphephile wamehlo, anokusebenza kahle okuphezulu kokubonakalayo. Lokhu kukhombisa i-ND: Ukuguquguquka okuguquguqukayo kanye nokwethenjwa njengokuthola okuphakathi kwezicelo ezihlukile ze-Laser (Zhang et al., 2013).
3.Longevity kanye nekhwalithi ye-beam: Ukucwaninga nge-diode esebenza kahle kakhulu, i-diode, i-ag laser igcizelele isikhathi eside sayo nokusebenza okungaguquki, okukhombisa ukufaneleka kwe-ND: ukufaneleka kwe-ND: ukufaneleka kwe-lases okudingakalayo. Ucwaningo lubike ukuthi uphinde wabikwa ukuthi u-Extended Operation enezinye izibhamu ezingaphezu kuka-4,8 x
Ukusebenza okuqhubekayo okuqhubekayo okuqhubekayo okuqhubekayo:Ucwaningo lukhombisile ukusebenza kahle okuqhubekayo okuqhubekayo (CW) kokusebenza kwe-ND: Ama-Lag Lasers, aqokomisa ukusebenza kwawo njengethonya eliphakathi ezinhlelweni zama-laser we-diode-pumpled laser. Lokhu kufaka phakathi ukuguqulwa okuphezulu kokuguqulwa kwe-optical kokuguquguquka kanye nokungabi nazikhathi ezithambile, kuphinde kwafakazelwa ukufaneleka kwe-ND: i-yag yokusebenza kahle kwe-laser (i-zhu et al., 2013).

Inhlanganisela yokusebenza kahle okuphezulu, okukhishwa kwamandla, ukuguquguquka kwamandla, ukuthembeka, isikhathi eside, futhi ikhwalithi enhle kakhulu ye-ND yenza i-ND: yag a inzuzo ephakathi nendawo yamamojula we-semiconductor we-semiconductor-pompos
