Ithimba laseShayina lithuthukise i-Raman fiber laser enamandla amakhulu eguquguqukayo enamandla amakhulu ebhendi engu-1.2μm

Ithimba laseShayina lenze i-Raman enamandla amakhulu eguquguqukayo enobubanzi obuyi-1.2μmi-fiber laser

Imithombo ye-laserEzisebenza ebhendini engu-1.2μm zinezinhlelo zokusebenza ezihlukile ekwelashweni kwe-photodynamic, ekuxilongweni kwezokwelapha, kanye nasekuzweleni umoya-mpilo. Ngaphezu kwalokho, zingasetshenziswa njengemithombo yepompo yokukhiqiza ukukhanya okuphakathi kwe-infrared kanye nokukhiqiza ukukhanya okubonakalayo ngokuphindaphindwa kwemvamisa. Ama-Laser ebhendini engu-1.2μm afinyelelwe ngezindlela ezahlukene.ama-laser e-solid-state, kufaka phakathiama-laser e-semiconductor, ama-laser edayimane iRaman, kanye nama-laser e-fiber. Phakathi kwala ma-laser amathathu, i-laser ye-fiber inezinzuzo zesakhiwo esilula, ikhwalithi enhle ye-beam kanye nokusebenza okuguquguqukayo, okwenza kube ukukhetha okungcono kakhulu ukukhiqiza i-laser yebhendi engu-1.2μm.
Muva nje, ithimba locwaningo eliholwa nguSolwazi Pu Zhou eShayina linesithakazelo kuma-laser e-fiber anamandla aphezulu ebhendini engu-1.2μm. I-fiber yamanje enamandla aphezuluama-laserikakhulukazi ama-laser e-fiber afakwe i-ytterbium ebhendini engu-1 μm, futhi amandla aphezulu okukhipha ebhendini engu-1.2 μm anqunyelwe ezingeni lika-10 W. Umsebenzi wabo, onesihloko esithi “I-laser ye-fiber ye-Raman enamandla amakhulu okuguqulwa kubhendini ye-wave engu-1.2 μm,” wanyatheliswa ku-Frontiers ofOptoelectronics.

ISITHOMBE 1: (a) Ukusethwa kokuhlola kwe-Raman fiber amplifier enamandla amakhulu kanye (b) i-Raman fiber seed laser engaguquki engaguquki ku-1.2 μm band. I-PDF: i-fiber efakwe i-phosphorus; I-QBH: I-Quartz bulk; I-WDM: I-Wavelength division multiplexer; I-SFS: umthombo wokukhanya we-fiber superfluorescent; I-P1: i-port 1; I-P2: i-port 2. I-P3: ikhombisa i-port 3. Umthombo: UZhang Yang nabanye, I-Raman fiber laser enamandla aphezulu angaguquki ku-1.2μm waveband, I-Frontiers of Optoelectronics (2024).
Umqondo uwukusebenzisa umphumela wokuhlakaza we-Raman ovuselelwe ku-fiber engasebenzi ukuze kukhiqizwe i-laser enamandla aphezulu ebhendini engu-1.2μm. Ukuhlakaza kwe-Raman okuvuselelwe kuwumphumela ongewona owe-oda lesithathu oguqula ama-photon abe ama-wavelength amade.

Umfanekiso 2: Ama-spectra okukhipha i-RFL angahleliwe angaguquki ku-(a) 1065-1074 nm kanye (b) ama-wavelength ephampu angu-1077 nm (Δλ ibhekisela kububanzi bomugqa obungu-3 dB). Umthombo: Zhang Yang et al., I-Raman fiber laser enamandla amakhulu angaguquki ku-1.2μm waveband, i-Frontiers of Optoelectronics (2024).
Abacwaningi basebenzise umphumela wokuhlakazeka kweRaman ovuselelwe ku-fiber efakwe i-phosphorus ukuguqula i-fiber efakwe i-ytterbium enamandla aphezulu ku-band engu-1 μm ibe yi-band engu-1.2 μm. Isignali yeRaman enamandla afinyelela ku-735.8 W itholakale ku-1252.7 nm, okuyiwona mandla aphezulu okukhipha we-laser ye-fiber ye-band engu-1.2 μm ebikwe kuze kube manje.

Umfanekiso 3: (a) Amandla okukhipha aphezulu kanye ne-spectrum yokukhipha ejwayelekile kuma-wavelength ahlukene esignali. (b) I-spectrum yokukhipha ephelele kuma-wavelength ahlukene esignali, ku-dB (Δλ ibhekisela ku-linewidth engu-3 dB).
