Goynta laysarka Fiber iyo Caafimaadka

Fiber laser goynta iyo daawada, Fiber laser goynta mishiinka waa doped fiber laftiisa sida walaxda shaqada, iyo fiber laser goynta mashiinka laftiisa, laakiin sidoo kale ka ciyaara doorka hagaha mawjada laser adag-state.Resonator, wuxuu ka kooban yahay walaxda shaqada, bamka isha saddex qaybood oo aasaasi ah.Sanadihii la soo dhaafay, laser fiber ee beeraha warshadaha marka lagu daro tiro balaadhan oo ah codsiyada, iyo caanka sii kordhaya ee duurka ku caafimaadka.

Xarunta Tiknoolajiyada Fiber, Jaamacadda Sydney, Australia (OFT C) ee Stuart Jackson ayaa yiri: "Mashiinka goynta fiber-ka laser-ka ee codsiyada qalliinka, waa muhiim in la isku dhejiyo leysarka, dayactirka yar, waxtarka sare ee waxtarka sare iyo sifooyinka kuleylka wanaagsan ee laser fiber.iyaga oo si gaar ah ugu habboon codsiyada qalliinka sababtoo ah waxay isticmaalayaan diode-pumped, sidaas darteed waa mid aad u cufan.Qaabka fiber-ka marka loo eego walxaha adag ee laysarka ayaa ka sarreeya sababtoo ah waxay fududaysay baahida loo qabo fibreerka gudbinta dheeraadka ah, taas oo hoos u dhigaysa qiimaha waxayna yaraynaysaa isku-darka nidaamka".

Mashiinka goynta Fiber laser in 1963 by Elias Spritzer.Ka hor inta aan ugu dambeyntii gelin isticmaalka ganacsiga, ka dib ku dhawaad ​​laba sano oo waqti horumarinta.Horaantii, isticmaalka leysarka diode-ka-hal-habka ah ayaa bamgareeyay, kaliya shucaac tobanaan millilitir ah.Laakiin waxa ay leedahay wax badan oo ka mid ah dadka isticmaala weli soo jiidasho leh, sababtoo ah faa'iidooyinkooda sare, waxay ka dhigi kartaa wax badan oo ka mid ah hawlgalka joogtada ah ee hal hab ee ion dhulka dhif ah, taas oo ah laser crystal aan la gaari karin.1990, lasers fiber si loo gaaro heerka wax soo saarka leap-watt, ka dib, ayaa sheegay in koronto-soo-saarka erbium-doped fiber laser kor u kaca 4 W, horumarkan maanta waxaan aragnaa awooda 10 W iyo ka sarreeya aasaaska laser-ka fiber hal-mode.

Mashiinka goynta laser fiber, fiber laftiisa u dhaqmo sida dalool resonant ah.Qalabkani guud ahaan waxa uu ka kooban yahay erbium doped hal-mode xudunta u ah ytterbium (ama isku-darka), ama curiyaha dhulka naadir ah.Tamarta ka timaadda isha iftiinka adag, waxa ay ku xidhan tahay dahaadhka fiber-ka, ka dibna gudaha ubucda, bamku waxa uu sameeyaa atomyada pant.Dhinaca caafimaadka, hirarka dhererka loogu baahan yahay waa: 1.3μm band loogu talagalay sawir-qaadista, 1.5μm (ugu sarreysa nuugista biyaha) -4μm band ee qalliinka, oo u dhexeeya baaxadda awoodda millilitir ilaa in ka badan 100 W.

Jackson wuxuu yiri: "Isticmaalka CW lasers, codsiyada biomedical, gaar ahaan wax kasta oo awood sare leh CW lasers, waxay ka faa'iideysan karaan mashiinka goynta laser fiber-ka ee mashiinka goynta fibre-ga wuxuu bixiyaa waxtar sare, kala duwanaansho ballaaran, iyo dhammaan wax soo saarka.kala duwanaanta korantadu waxay leedahay faa'iido tayo fiican leh, gaar ahaan caan ah;si laser-ka fiber-ka uu u kala duwan yahay codsiyada caafimaadku ay sii wadaan inay sii ballaariyaan."
