Iqembu laseChina lisungule i-A 1.2μM Band High-Power TunAble Ramani-fiber laser

Imithombo ye-LaserUkusebenza kubhendi engu-1.2μm kunezicelo ezithile eziyingqayizivele ekwelashweni kwe-PhotoDoynamic, ukuxilongwa kwe-biomedical, kanye nokuzwa umoya-mpilo. Ngaphezu kwalokho, zingasetshenziswa njengemithombo yamaphampu yesizukulwane sepharamitha sokukhanya okuphakathi nendawo kanye nokukhiqiza isibani esibonakalayo yimvamisa ephinda kabili. Ama-lasers ebhendi le-1.2 μm atholwe ngehlukileama-lasers aqinile wombuso, kufaka phakathiAma-Semiconductor Lasers, ama-lasers e-Diamond Raman lasers, kanye ne-fiber lasers. Phakathi kwalawa ma-lasers amathathu, i-fiber laser inezinzuzo zesakhiwo esilula, ikhwalithi enhle nokusebenza okuguqukayo, okwenza kube yisinqumo esihle kakhulu sokukhiqiza i-1.2μm Band Laser.
Muva nje, iqembu lokucwaninga eliholwa nguProfesa Pu Zhou eChina linentshisekelo kuma-lesters aphezulu we-fiber ebhendi ka-1.2μm. I-fiber ephezulu yamanjeamachwebaikakhulukazi i-yterterbium-doped fiber lasers ku-1 μm band, futhi amandla aphezulu okukhipha kubhendi ka-1.2 μm akhawulelwe ezingeni le-10 W. Umsebenzi wabo, onesihloko esithi High Power Tunes Fun Raman at 1.2μm Wavesband, "kushicilelwe emingceleni yeI-OptoElectronics.

Fig. 1: (a) Ukusethwa kokuhlola kwe-amplifier ephezulu ye-raman ye-raman ye-raman kanye (b) noshintsho olungahleliwe raban I-PDF: I-fiber ye-phosphorus-doped; QBH: I-Quartz Bulk; I-WDM: I-Wavelength Division Multenxer; I-SFS: Umthombo wokukhanya kwe-superfluescent; I-P1: IPort 1; I-P2: IPort 2. I-P3: Ibonisa iPort 3. Umthombo: Umthombo: I-Zhang Yang et al.
Umqondo ukusebenzisa umphumela ovuselelekile wokusakazeka we-raman ku-fiber engaguquki ukukhiqiza i-laser ephezulu yamandla ku-1.2μm band. Ukuhlakazeka okuvuselelwa kweRaman ngumphumela we-oda wesithathu oguqula ama-photons kuma-wavelength amade.

Abaphenyi basebenzise umphumela ovuselelwayo wokusakazeka weRaman ku-fiber phosphorus-doped fiber ukuguqula i-yterbium-doped fiber ephezulu ye-ytterbium-doped fiber ku-1 μm band ibe yiqembu eli-1,2 μm. Isiginali yeRaman enamandla afinyelela ku-735.8 W atholakala ku-1252.7 NM, okuwukuphakamisa okuphezulu kakhulu kokukhishwa kwe-1.2 μm band Laser okubikwe kuze kube manje.
