Waa maxay Faa'iidada Laser Dhexdhexaad?

Dhexdhexaadka faa'iidada laysarka waa shay kor u qaada iftiinka iyadoo la kicinayo qiiqa. Marka atamka ama molecules-yada dhexdhexaadka ah ay ku faraxsan yihiin heerarka tamarta sare, waxay sii dayn karaan sawir-qaade dherer gaar ah marka ay ku soo noqdaan xaalad tamar hoose. Habkani wuxuu kor u qaadayaa iftiinka dhex mara dhexdhexaadka, kaas oo aasaas u ah hawlgalka laysarka.

Waa maxay Faa'iidada Caadiga ah?

Dhexdhexaadinta faa'iidada waa kala duwanaan kartaa, oo ay ku jiraangaasaska, dareereyaal (midabyo), adage(crystals ama muraayadaha lagu qurxiyey aions bir dhif ah ama dhul-wareeg ah), iyo semiconductors.Laser-state adag, tusaale ahaan, inta badan isticmaal crystals sida Nd: YAG (Neodymium-doped Yttrium Aluminum Garnet) ama muraayadaha lagu qurxiyey walxo dhif ah oo dhulka ah. Laysarada dheeha waxay isticmaalaan midabyo organic ah oo lagu milmay, iyo laysarka gaasku waxay isticmaalaan gaas ama gaas isku dhafan.

Farqiga u dhexeeya Nd (Neodymium), Er (Erbium), iyo Yb (Ytterbium) sida dhexdhexaadinta

ugu horrayn waxay la xidhiidhaa hirarka dhaadheer ee sii daaya, hababka wareejinta tamarta, iyo codsiyada, gaar ahaan marka la eego macnaha guud ee qalabka leysarka.

Mawjadaha sii daaya:

Erbium wuxuu caadi ahaan sii daayaa 1.55 µm, kaas oo ku yaal gobolka badbaadada indhaha oo aad waxtar u leh codsiyada isgaarsiinta sababtoo ah luminta fiilooyinka indhaha (Gong et al., 2016).

- Yb: Ytterbium wuxuu inta badan sii daayaa qiyaastii 1.0 ilaa 1.1 µm, taas oo ka dhigaysa mid ku habboon codsiyo kala duwan, oo ay ku jiraan laysarrada awoodda sare leh iyo amplifiers. Yb inta badan waxaa loo adeegsadaa dareen ahaan Er si kor loogu qaado waxtarka aaladaha Er-doped iyadoo tamarta laga wareejinayo Yb loona wareejiyo Er.

- Nd: Qalabka neodymium-doped sida caadiga ah waxay sii daayaan qiyaastii 1.06 µm. Nd:YAG, tusaale ahaan, waxa ay caan ku tahay hufnaanteeda waxaana si weyn loogu isticmaalaa laysarka warshadaha iyo caafimaadka labadaba (Y. Chang et al., 2009).

Hababka Wareejinta Tamarta:

- Er iyo Yb Co-doping: Isku-dubaridka Er iyo Yb ee dhexdhexaadiyaha martida loo yahay ayaa faa'iido u leh kor u qaadista qiiqa 1.5-1.6 µm. Yb wuxuu u shaqeeyaa sidii dareen wax ku ool ah oo loogu talagalay Er isagoo nuugaya iftiinka bamka iyo u wareejinta tamarta Er ions, taasoo horseedaysa sii daynta la kordhiyey ee kooxda isgaarsiinta. Wareejinta tamarta ayaa muhiim u ah hawlgalka Er-doped fiber amplifiers (EDFA) (DK Vysokikh et al., 2023).

- Nd: Nd caadiyan uma baahna dareen-celiye sida Yb ee hababka Er-doped. Waxtarka Nd waxaa laga soo qaatay nuugista tooska ah ee iftiinka bamka iyo sii daynta ku xigta, taas oo ka dhigaysa mid dhexdhexaad ah oo faa'iido layser ah oo toos ah oo hufan.

Codsiyada:

- Er:Inta badan loo isticmaalo isgaarsiinta sababtoo ah sii daynteeda 1.55 µm, taas oo ku beegan daaqada lumista ugu yar ee fiilooyinka silica. Dhexdhexaadiyaha faa'iidada Er-doped ayaa muhiim u ah cod-weyneyaasha indhaha iyo laysarka ee nidaamyada isgaarsiinta fiber optic-ga fog.

- Yb:Badanaa waxaa loo isticmaalaa codsiyada awoodda sare leh sababtoo ah qaab-dhismeedkeeda elektaroonigga ah ee fudud oo u oggolaanaya bamgareynta diode hufan iyo soo saarista koronto sare. Qalabka Yb-doped ayaa sidoo kale loo isticmaalaa si kor loogu qaado waxqabadka nidaamyada Er-doped.

- Nd: Si fiican ugu habboon codsiyada kala duwan, laga bilaabo goynta warshadaha iyo alxanka ilaa lasers caafimaad. Nd:YAG lasers ayaa si gaar ah loogu qiimeeyaa waxtarkooda, awooddooda, iyo wax-qabadkooda.

Maxaynu Nd:YAG u dooranay dhexdhexaadka faa'iidada leysarka DPSS

Laysarka DPSS waa nooc ka mid ah laysarka isticmaala dhexdhexaad-helid dawladeed oo adag (sida Nd: YAG) oo ay ku shubto dareeraha leysarka semiconductor. Farsamadani waxay u oggolaanaysaa leysarka is haysta, wax ku ool ah oo awood u leh inay soo saaraan alwaaxyo tayo sare leh oo la arki karo-infrared spectrum. Maqaal faahfaahsan, waxaa laga yaabaa inaad tixgeliso inaad ka dhex raadiso kaydadka sayniska ee sumcadda leh ama daabacayaasha dib u eegis dhamaystiran oo ku saabsan tignoolajiyada laysarka DPSS.

Nd:YAG waxaa badanaa loo istcimaalaa faa'iido dhexdhexaad ah modules-ka laser-ka-bambeeya dhowr sababood awgood, sida lagu muujiyey daraasado kala duwan:

1. Waxtarka Sare iyo Korontada: Naqshadeynta iyo jilitaanka diode-dhinac-bamgareynta Nd: YAG laser moduleka ayaa muujiyay waxtarka muhiimka ah, oo leh diode dhinaca bamgareysan Nd: YAG laser oo bixisa celceliska celceliska celceliska 220 W iyada oo la ilaalinayo tamar joogto ah halkii garaaca oo kala duwan. Tani waxay muujinaysaa waxtarka sare iyo kartida wax-soo-saarka awoodda sare ee Nd: YAG lasers marka lagu shubo diodes (Lera et al., 2016).
2.Dabacsanaan iyo Kalsooni Hawleed: Nd:Yag ceramics ayaa la muujiyay inay si hufan ugu shaqeeyaan mawjadaha dhaadheer ee kala duwan, oo ay ku jiraan mowjadaha badqabka indhaha, oo leh hufnaan sare-ilaa-optical. Tani waxay muujinaysaa Nd: Kala duwanaanshaha YAG iyo isku hallaynta sida dhexdhexaadinta faa'iidada ee codsiyada laser kala duwan (Zhang et al., 2013).
3.Dheer iyo Tayada Beam: Cilmi-baadhis ku saabsan wax-qabad heer sare ah, diode-pumped, Nd: YAG laser waxay xoojisay cimri-dhererkeeda iyo waxqabadkeeda joogtada ah, taas oo muujinaysa Nd: YAG ku habboonaanta codsiyada u baahan ilo layser ah oo waara oo lagu kalsoonaan karo. Daraasadu waxay sheegtay hawlgal dheerad ah oo leh in ka badan 4.8 x 10 ^ 9 darbo aan lahayn waxyeelo indhaha, ilaalinta tayada iftiinka wanaagsan (Coyle et al., 2004).
4.Hawlgalka hir-mawjadaha joogtada ah ee Waxtarka leh:Daraasaduhu waxay muujiyeen waxqabadka aadka u hufan ee mawjada joogtada ah (CW) ee Nd: YAG lasers, oo muujinaya waxtarkooda sida dhexdhexaadka ah ee hababka laser-pamped diode-pamped. Tan waxaa ka mid ah in la gaaro wax ku oolnimada beddelka indhaha sare iyo waxtarka jiirada, caddayn dheeraad ah ku habboonaanta Nd: YAG ee codsiyada laser waxtarka sare leh (Zhu et al., 2013).

Isku dhafka waxtarka sare leh, wax soo saarka awoodda, dabacsanaanta hawlgalka, isku hallaynta, cimri dhererka, iyo tayada iftiinka wanaagsan waxay ka dhigaysaa Nd: YAG mid dhexdhexaad ah oo faa'iido leh oo ku jira qaybaha laser-ka ee semiconductor-pumped ee codsiyada kala duwan.
