- Shuruudaha Isha Bamka Fiber Lasers
Diodes LaserSida Ilaha Pump:Fiber lasers inta badan waxay u isticmaalaan diodes laser sida isha matoorka sababtoo ah waxtarkooda, cabbirkooda is haysta, iyo awoodda ay u leeyihiin inay soo saaraan hirar gaar ah oo iftiin ah oo u dhigma xajmiga nuugista ee fiber-ka doped.Doorashada hirarka dhererka diode laser waa muhiim;Tusaale ahaan, dopant-ka caadiga ah ee lasers-ka fiber-ka waa Ytterbium (Yb), kaas oo leh nuugista ugu sarreysa ee qiyaastii 976 nm.Sidaa darteed, diodes-ka laysarka ee ka soo baxaya mawjaddan dhererka ama u dhow ayaa loo door bidaa in lagu shubo leysarka fiber-ka Yb-doped.
Naqshadaynta Fiber-Labba-Labba ah:Si loo kordhiyo waxtarka nuugista iftiinka ee bamka laser diodes, laser-ka fiber-ka ayaa inta badan isticmaala naqshad labajibbaaran.Xudunta gudaha waxaa lagu dahaadhay dhexdhexaadiyaha laysarka ee firfircoon (tusaale, Yb), halka dibadda, lakabka daboolka weyni hagayo iftiinka bamka.Xuddunta waxay nuugtaa iftiinka bamka waxayna soo saartaa ficilka laysarka, halka daboolku u oggolaanayaa qadar aad u badan oo iftiinka bamka ah si uu ula falgalo xudunta, kor u qaadista waxtarka.
Mawjadaha Dhererka iyo Isku-xidhka Waxtarka: Bamgareynta waxtarka leh waxay u baahan tahay ma aha oo kaliya xulashada diodes laser leh mawjadaha dhererka ku habboon, laakiin sidoo kale hagaajinta waxtarka isku-xidhka ee u dhexeeya daloodhka iyo fiber-ka.Tani waxay ku lug leedahay toosinta taxadir leh iyo isticmaalka qaybaha indhaha sida muraayadaha iyo lamaanayaasha si loo hubiyo in ugu badnaan iftiinka bamka lagu duro xudunta fiber-ka ama daboolka.
-Laser-State-GobolShuruudaha Isha Pump
Bamgareynta indhaha:Diodes-ka laysarka ka sokow, laysarka dawlad- adag (ay ku jiraan laysarka badan sida Nd:YAG) waxa si mug leh loogu shubi karaa laambado toos ah ama nalalka arc.Laambadahani waxay sii daayaan iftiin ballaadhan, qayb ka mid ah kuwaas oo u dhigma xargaha nuugista ee dhexdhexaadiyaha laysarka.Iyadoo ay ka tayo yar tahay bamgareynta diode laser, habkani wuxuu ku siin karaa tamarta garaaca wadnaha oo aad u sarreeya, taasoo ka dhigaysa mid ku habboon codsiyada u baahan awoodda ugu sarreysa.
Habaynta Isha Pump:Habaynta isha bamka ee laser-gobolka adag waxay si weyn u saameyn kartaa waxqabadkooda.Bamgareynta dhamaadka iyo bamgareynta dhinaca ayaa ah habayn caadi ah.Dhamaadka bamgareynta, halkaasoo nalka bamka lagu hagayo dhidibka indhaha ee dhexdhexaadiyaha laysarka, wuxuu bixiyaa isugeyn wanaagsan oo u dhexeeya iftiinka bamka iyo habka laysarka, taasoo horseedaysa waxtar sare.Bamgareynta dhinaca, iyada oo ay suurtogal tahay in ay tayadeedu yar tahay, way ka sahlan tahay waxayna siin kartaa tamar sare guud ahaan ulo-ballaaran ama saqafyada.
Maareynta kulaylka:Fiber iyo laser-state-ada adag labaduba waxay u baahan yihiin maamul kuleyl oo wax ku ool ah si ay u xakameeyaan kulaylka ay dhaliyaan ilaha matoorka.Laysarka fiber-ka, aagga dusha sare ee fiber-ku wuxuu caawiyaa kala-baxa kulaylka.Laydhka adag ee gobolka, nidaamyada qaboojinta (sida qaboojinta biyaha) ayaa lagama maarmaan u ah in la ilaaliyo hawlgalka xasilloon oo looga hortago lensiga kuleylka ama waxyeellada dhexdhexaadiyaha laysarka.
