Chikwata chekuChina chakagadzira Raman ine simba guru inogadziriswa ine bhendi re1.2μmlaser yefaibha

Manyuko eLaserMashandiro awo anoshanda mubhendi re1.2μm ane mamwe mashandisirwo akasiyana mukurapa ne photodynamic, kuongorora biomedical, uye kunzwa oxygen. Pamusoro pezvo, anogona kushandiswa semapombi ekugadzira chiedza chepakati pe infrared uye kugadzira chiedza chinoonekwa nekuwedzera frequency. MaLaser ari mubhendi re1.2μm akaitwa nemaitiro akasiyana.ma laser emamiriro akasimba, kusanganisiralaser dze semiconductor, madhaimani eRaman lasers, uye mafiber lasers. Pakati pema lasers matatu aya, fiber laser ine zvakanakira zvechimiro chiri nyore, mhando yakanaka yedanda uye mashandiro anochinjika, izvo zvinoita kuti ive sarudzo yakanakisa yekugadzira 1.2μm band laser.
Munguva pfupi yapfuura, timu yekutsvagisa inotungamirwa naProfessor Pu Zhou kuChina iri kufarira malaser ane simba guru mubhendi re1.2μm. Fiber ine simba guru iripo iye zvino.lasersMazhinji acho ari ma-fiber laser ane ytterbium-doped mubhendi re1 μm, uye simba guru rekuburitsa mubhendi re1.2 μm rakaganhurirwa padanho re10 W. Basa ravo, rine musoro unoti “Raman fiber laser ine simba guru pabhendi re1.2 μm,” rakabudiswa muFrontiers ofZvemagetsi zveOptoelectronics.

Mufananidzo 1: (a) Kuedza kwekugadzira amplifier yeRaman fiber inogadziriswa ine simba guru uye (b) laser yeRaman fiber seed laser inogadziriswa pa 1.2 μm band. PDF: fiber ine phosphorus-doped; QBH: Quartz bulk; WDM: Wavelength division multiplexer; SFS: superfluorescent fiber light source; P1: port 1; P2: port 2. P3: inoratidza port 3.

Pfungwa yacho ndeyekushandisa simba reRaman scattering rinomutswa mu passive fiber kugadzira laser ine simba guru mubhendi re1.2μm. Stimulated Raman scattering ibasa rechitatu-order nonlinear rinoshandura maphoton kuita mawavelength akareba.

Mufananidzo 2: Magirazi emagetsi anogadziriswa eRFL asingatarisirwi pa (a) 1065-1074 nm uye (b) 1077 nm marefu emvura (Δλ zvinoreva 3 dB linewidth). Chitubu: Zhang Yang et al., Raman fiber laser inogadziriswa ine simba guru pa1.2μm waveband, Frontiers of Optoelectronics (2024).
Vaongorori vakashandisa simba rekupararira kweRaman rakakurudzirwa mufiber ine phosphorus kuti vashandure fiber ine ytterbium ine simba guru pa1 μm band kuita 1.2 μm band. Chiratidzo cheRaman chine simba rinosvika 735.8 W chakawanikwa pa1252.7 nm, inova ndiyo simba guru rekuburitsa re1.2 μm band fiber laser yakataurwa kusvika pari zvino.

Mufananidzo 3: (a) Simba guru rekuburitsa uye spectrum inobuda yakajairika pawavelengths dzakasiyana dzechiratidzo. (b) Spectramu yakazara yekuburitsa pawavelengths dzakasiyana dzechiratidzo, mu dB (Δλ inoreva 3 dB linewidth).
