Itsinda ry'Abashinwa ryakoze Raman ifite imbaraga nyinshi ishobora guhindurwa ifite uburebure bwa 1.2μmlaser ya fibre

Inkomoko ya laserIkora mu gice cya 1.2μm ifite akamaro kadasanzwe mu buvuzi bushingiye ku isanzure, gusuzuma indwara, no kumenya umwuka wa ogisijeni. Byongeye kandi, ishobora gukoreshwa nk'isoko ry'ipompo mu gukora urumuri rwo hagati mu ntera ya infrared no mu gutanga urumuri rugaragara binyuze mu kwikuba kabiri inshuro. Lazeri mu gice cya 1.2μm yagezweho hakoreshejwe uburyo butandukanye.laser za state solid, harimolaser za semiconductor, laser za diyama Raman, na laser za fibre. Muri izi laser eshatu, laser ya fibre ifite ibyiza byo kuba imiterere yoroshye, ubwiza bwiza bw'imirasire n'imikorere yoroshye, bituma iba amahitamo meza yo gukora laser ya band ya 1.2μm.
Vuba aha, itsinda ry’ubushakashatsi riyobowe na Porofeseri Pu Zhou mu Bushinwa rishishikajwe na lasers zifite ingufu nyinshi muri bande ya 1.2μm. Fibre ifite ingufu nyinshi ubuimirasire ya laserahanini ni laser za fibre zikozwe muri ytterbium mu gice cya 1 μm, kandi imbaraga ntarengwa zo gutanga umusaruro mu gice cya 1.2 μm zigarukira ku rugero rwa 10 W. Umurimo wabo, witwa “Laser ya fibre ya Raman ifite imbaraga nyinshi ku gice cya 1.2 μm,” wasohotse mu kinyamakuru Frontiers ofIkoranabuhanga rya Optoelectronics.

ISHUSHO YA 1: (a) Gushyiraho igerageza rya amplifier ya fibre ya Raman ishobora guhindurwa ifite imbaraga nyinshi na (b) laser ya random ya Raman ishobora guhindurwa ku murongo wa 1.2 μm. PDF: fibre ivanze na fosifore; QBH: Quartz bulk; WDM: Wavelength division multiplexer; SFS: superfluorescent fiber light source; P1: port 1; P2: port 2. P3: igaragaza port 3.

Igitekerezo ni ugukoresha ingaruka zo gukwirakwiza za Raman muri fibre idakora kugira ngo hakorwe laser ifite imbaraga nyinshi muri bande ya 1.2μm. Gukwirakwiza kwa Raman mu buryo bwa stimulated ni ingaruka ya gatatu idakora ku murongo ihindura fotoni mu burebure bw'uburebure.

Ishusho ya 2: Spektara y'umusaruro wa RFL ishobora guhindurwa ku buryo butunguranye kuri (a) 1065-1074 nm na (b) uburebure bw'umurambararo wa pompe ya 1077 nm (Δλ yerekeza ku bugari bwa 3 dB). Inkomoko: Zhang Yang et al., Laser ya Raman ikoreshwa cyane ku bunini bwa 1.2μm, Frontiers of Optoelectronics (2024).
Abashakashatsi bakoresheje uburyo bwa Raman bwo gukwirakwiza fibre irimo fosifore kugira ngo bahindure fibre ifite imbaraga nyinshi ya ytterbium kuri bande ya 1 μm igere kuri bande ya 1.2 μm. Ikimenyetso cya Raman gifite imbaraga zigera kuri 735.8 W cyabonetse kuri 1252.7 nm, ari na cyo gitanga umusaruro mwinshi kurusha ibindi byose byavuzwe kugeza ubu.

Ishusho ya 3: (a) Ingufu ntarengwa zo gusohora n'umuvuduko usanzwe ukoreshwa ku bunini bw'urumuri rw'ibimenyetso bitandukanye. (b) Umuvuduko wuzuye ukoreshwa ku bunini bw'urumuri rw'ibimenyetso bitandukanye, muri dB (Δλ yerekeza ku bugari bwa 3 dB).
