Koox Shiinees ah ayaa soo saaray 1.2μm oo awood-sare oo koronto ah oo raman ah oo raman ahFiber Laser

Ilaha laserKa shaqeynta 1.2μm kooxda ah waxay leeyihiin xoogaa codsiyo gaar ah oo ku jira daweynta sawir-gacmeedka, baaritaanka biomesicalka, iyo dareenka ogsijiinta. Intaas waxaa sii dheer, waxaa loo isticmaali karaa ilo biyo ah oo loogu talagalay jiilka taariikhiga ah ee iftiinka badhtamaha iyo abuurista iftiin muuqda oo labanlaab ah. Lasers ee 1.2 μm puord-ka ayaa lagu gaadhay kala duwanXoogga adag ee gobolka, oo ay ku jiraanSemiconductor Losers, dheeman Ranlan Rans, iyo Fiber Lasers. Saddexdaas Laasers ee ka mid ah, fiber laser wuxuu leeyahay faa'iidooyinka qaabdhismeedka fudud, oo ah tayo tayo leh iyo hawlgal dabacsan, kaas oo ka dhigaya doorashada ugu fiican ee ah in la soo saaro 1.2μm band laser.
Dhawaan, kooxda cilmi baarista ee ay hogaaminayeen Professor PO Professor PO POS Zhou ee Shiinaha ayaa danaynaya in ay ku jirto fiber-ka-sarreenka sare ee shanta-sare ee 1.2μm band. Fibradda awoodda sare ee hadda jirtalasersinta badan waa yareynta fiber-ka-fiber ee 1 μM, iyo awoodda ugu badan ee soosaarka ee 1.2 μM prods-ka 1.2 μM waxay ku hayaan "Awoodda sare ee Raman Fiber Liig-ga," waxaa lagu daabacay xuduudahaOptoelectronics.

Fikradda ayaa ah in la isticmaalo saameynta ugu kala fogayn ee Ramalka ah ee Ramalka ku dhexjirta fiber aan tooska ahayn si loo abuuro laser awood sare leh oo ku jira kooxda 1.2μm. Soo kicinta Raean Frat fir firsit waa amar-rasmi ah oo aan toos ahayn saameyn ku yeelanaya sawirro u beddelaya sawirro dheer.

Cilmi baadhayaashu waxay u adeegsadeen saameynta ugu kala fogayn ee Ramalka ah ee finan-ka-fosfooraska fosfooraska-fosfooraska ah si ay u beddelaan fiber-saderbium-yerbium-ka badan ee 1 μm band to 1.2 μm band. Signal Raman oo leh awood ilaa 735.8 W ayaa laga helay 1252.7 NM, kaasoo ah awoodda ugu sareysa ee soosaarka ah ee 1.2 μM warqad warqad warqad fiber ah oo la soo sheegay.
