Koox Shiinees ah ayaa soo saartay laser Raman fiber ah oo awood sare leh oo 1.2μm ah oo lagu hagaajin karo

Koox Shiinees ah ayaa soo saartay Raman awood sare leh oo cabbirkiisu yahay 1.2μm oo ah muusig tayo sare leh oo la hagaajin karolaysarka fiber-ka

Ilaha laysarkaKa shaqaynta xarigga 1.2μm waxay leeyihiin codsiyo gaar ah oo ku saabsan daaweynta sawir-qaadista, ogaanshaha bayoolajiga, iyo dareemaha oksijiinta. Intaa waxaa dheer, waxaa loo isticmaali karaa ilo bambo si loo soo saaro iftiinka dhexe ee infrared-ka iyo in la soo saaro iftiin muuqda iyadoo la labanlaabay tirada soo noqnoqoshada. Laser-yada ku jira xarigga 1.2 μm waxaa lagu gaaray iyadoo la adeegsanayo habab kala duwan.laysarka adag, oo ay ku jiraanlaysarka semiconductor-ka, laysarka Raman ee dheemanka ah, iyo laysarka fiber-ka. Saddexdan laysar, laysarka fiber-ka ah wuxuu leeyahay faa'iidooyinka qaab-dhismeedka fudud, tayada iftiinka wanaagsan iyo hawlgalka dabacsan, taasoo ka dhigaysa doorashada ugu fiican ee lagu soo saaro laysarka band-ka 1.2μm.
Dhawaan, kooxda cilmi-baarista oo uu hoggaaminayo Professor Pu Zhou oo ku sugan Shiinaha ayaa xiisaynaya laser-ka fiber-ka ee awoodda sare leh ee ku jira xarigga 1.2μm.laysarkaInta badan waa leysar fiilooyin ah oo lagu dahaadhay ytterbium oo ku jira 1 μm, awoodda wax soo saarka ugu badan ee ku jirta 1.2 μm waxay ku kooban tahay heerka 10 W. Shaqadoodu, oo cinwaan looga dhigay "Laysar fiilooyin Raman oo awood sare leh oo lagu hagaajin karo 1.2 μm waveband," ayaa lagu daabacay Frontiers ofOptoelectronics.

Fikraddu waa in la isticmaalo saamaynta kala firdhinta Raman ee kicisa ee ku jirta fiilada aan firfircoonayn si loo soo saaro laysar awood sare leh oo ku jira xarigga 1.2μm. Kala firdhinta Raman ee kicisa waa saameyn aan toosnayn oo saddexaad ah oo u beddela fotonada hirarka dhaadheer.

Cilmi-baarayaashu waxay isticmaaleen saameynta kala firdhinta Raman ee kicisay ee ku jirta faybarka fosfooraska lagu dahaadhay si ay u beddelaan faybar ytterbium oo awood sare leh oo leh 1 μm band ilaa 1.2 μm band. Calaamad Raman oo leh awood ilaa 735.8 W ah ayaa laga helay 1252.7 nm, taas oo ah awoodda ugu sarreysa ee wax soo saarka laysarka fiber-ka ee 1.2 μm ee ilaa hadda la soo sheegay.
