Fiber LaserSi loo gaaro wax soo saarka laser-ka-dhererka dhexe, tallaabada ugu horreysa waa in la xusho sheyga fiberka ee ku habboon. In lagu dhex mariyo fiber-ka-dhabarka galab ee cratrared, matrix galaaska rubucku waa sheyga matrix-ka ugu caansan ee leh khasabka aad u yar ee gudbinta liidashada, awood farsamo oo lagu kalsoonaan karo iyo xasillooni darro heer sare ah. Si kastaba ha noqotee, sababtoo ah PHONONON ENESS (1150 CM-1), FARSAMADA FARSAMADA looma adeegsan karo gudbinta laser-ka-dhexda dhexe. Si loo gaaro khasaaraha hoose ee laser-ka hooseeya ee laser-ka-dhexda, waxaan u baahanahay inaan dib u dooranno ashyaa'da matrix-ga leh ee leh tamar hoose ee sawirka hoose, sida matrix galaaska sulride ama matrix galaaska fluoride. Fibriiska Sulfide Phononn Tamarta (qiyaastii 350 cm-1), laakiin waxay leedahay dhibaatada ah in feejignaanta isku-darka aan la kordhin karin, sidaa darteed uma fiicna in loo isticmaalo fiber-ka-helidda-ka-dhex-dhexaadka. In kasta oo ay ku jirto sunta galaas ee foloraydh waxyar ka sareeya tamar ka sarreysa (550 cm-1) marka loo eego substrate muraayadaha sulfide-ka, waxay sidoo kale ku gaari kartaa in khasaaro yar oo la-tanaasha ah oo leh wax ka yar 4 μm. Si ka sii muhiimsan, substrate galaas-ka-dhexaadka ah waxay ku guuleysan kartaa feejignaanta dhulka dushiisa ee dushiisa, taas oo laga yaabo in loo baahan yahay farriinta laserrared, tusaale ahaan, waxay awood u yeelatay inay ku guuleysato feejignaan isku-darka ah illaa 10 mol. Sidaa darteed, matrix galaaska Fluoride waa sheyga ugu habboon ee fiber-ka ugu habboon ee loo yaqaan 'fiber-ka' buluuga ah ee dhex gala.

Dhawaan, kooxda Professor Run Shuangchen iyo Professor Guo Chunyu oo ku sugan Shenzhen University ayaa sameeyay mid awood sare lehPulse Fiber LaserWaxay ka kooban tahay 2.8μm mode-qufulka er: zblan fiber oscillator, hal-mode er: zblan fiber preamplifier iyo mode-ka weyn ee garoonka ER: zblan fiber om ore-ka weyn.
Iyada oo ku saleysan is-miidaaminta is-miidaaminta iyo cod-weyn-weyneynta garaaca wadnaha-ka-dhexgalka ee 'State-ka-dhexda' State-ka-dhexda iyo jilitaanka ee qaabka loo yaqaan 'The Transpension Pukch', Nidaamyada Qabow ee Qabow ee Qabow-Gaaban ee Pull-Guud oo leh awood celcelis ahaan 8.12W iyo balac garaaca wadnaha 148 FS. Diiwaanka caalamiga ah ee awooda ugu sareeya celceliska ee ay gaareen kooxdan cilmi-baarista ah ayaa la sii cuslaaday.

Orodka ballaaran ee miraha weyn, oo ah labajibbaarane waaweyn Dhexroor weyn oo xudunta ah waxay ka dhigeysaa samaynta fiber-ka inay hoos udhacdo isku-darka aan tooska ahayn oo ay u adkeysan karto awoodda ugu sarreysa ee Pulek iyo soosaarka garaaca garaaca wadnaha. Labada daraf ee saqafka leh fiberka ayaa ku habboon daboolka Terminal ALF3.
