Siyakwamukela ku-Ruijie Laser

I-Optical fiber yomshini wokusika i-fiber laser iwuhlobo lwe-medium-infrared band laser ene-fiber laser njengento yokusebenza (inzuzo ephakathi).Ingahlukaniswa nge-laser ye-doped fibre yomhlaba engavamile, i-fiber optical nonlinear effect laser, i-single crystal fibre laser, ama-fiber arc lasers, njll..ngokusekelwe ekuvusweni kwenjabulo.Phakathi kwazo, ama-laser we-doped fiber lasers avuthwe kakhulu, njenge-doped erbium fiber amplifier (EDFA) asetshenziswe kabanzi ezinhlelweni zokuxhumana ze-optical fibre.Ama-laser e-fiber aphezulu asetshenziswa kakhulu kwezempi (i-photoelectric confrontation, ukutholwa kwe-laser, ukuxhumana nge-laser, njll.), ukucutshungulwa kwe-laser (ukumaka nge-laser, irobhothi le-laser, i-laser micromachining, njll.), ezokwelashwa neminye imikhakha.

I-fiber laser yenziwa i-SiO2 njenge-matrix material ye-glass fibre eqinile, okuyisimiso somhlahlandlela wokukhanya ukusebenzisa isimiso esiphelele sokubonisa ishubhu, okungukuthi, lapho ukukhanya kukhishwa ku-optical density medium of high refractive. inkomba kwenye yenkomba encane ye-refractive ene-engeli enkulu kune-engeli ebalulekile, ukuboniswa okuphelele kuzovela futhi ukukhanya kwesigameko kuzoboniswa ngokuphelele ku-optical density medium ye-high refractive index.Lapho ukukhanya kukhishwa kusukela ku-optical density medium (okungukuthi, inkomba ye-refractive yokukhanya okuphakathi inkulu) kuya ekuxhumaneni kwe-optical sparse medium (okungukuthi, inkomba ye-refractive yokukhanya incane phakathi nendawo), konke ukukhanya kuboniswa kubuyele endaweni yokuqala.Akukho ukukhanya okuzongena ku-optical density medium okunenkomba encane ye-refractive. I-Fiber engenalutho evamile ngokuvamile yakhiwa inkomba ephezulu yengilazi ephakathi (ububanzi obungu-4 ~ 62.5μm), inkomba yengilazi ye-silicon ye-refractive ephansi emaphakathi (ububanzi obuyingqikithi 125μm) kanye nembobo ye-resin eqiniswe ngaphandle.Imodi yokusabalalisa i-Fiber optic ingahlukaniswa ibe i-fiber yemodi eyodwa (SM) kanye ne-multi-mode (MM) fiber.I-fiber core diameter yemodi eyodwa, enobubanzi obuncane bomgogodla (4 ~ 12μm) ingasabalalisa imodeli eyodwa yokukhanya futhi ukuhlakazeka kwemodi kuncane.I-Multimode fiber core diameter ewugqinsi (ububanzi obukhulu kuno-50μm) ingasabalalisa izinhlobonhlobo zezindlela zokukhanya kuyilapho ukuhlakazeka kwe-intermodal kukukhudlwana.Ngokwezinga lokusatshalaliswa kwe-refractive, i-optic fiber ingahlukaniswa nge-step index (SI) fiber kanye ne-graded index (GI) fiber.

Thatha i-rare earth doped fiber lasers njengesibonelo, ehlanganiswe nezinhlayiya zomhlaba ezingavamile njengendlela yokuzuza, imicu ye-doped igxiliwe phakathi kwezibuko ezimbili ezakha i-resonant cavity.Ukukhanya kwepompo kuyisigameko esivela ku-M1 singene ku-fiber bese sikhiqiza i-laser kusuka ku-M2.Lapho ukukhanya kwepompo kudlula ku-fiber, kudonswa ama-ion omhlaba angavamile ku-fiber futhi ama-electron ajabulela izinga eliphezulu lokuvusa ukuze afinyelele ukuguquguquka kwezinhlayiyana zabantu.Izinhlayiya ezihlanekezelwe zidluliselwa ezingeni eliphezulu lamandla ziye endaweni engaphansi ngendlela yemisebe ukuze kukhiqizwe i-laser.
