Iqela laseTshayina liphuhlise iRaman ye-1.2μm yebhendi yamandla aphezuluifayibha laser

Imithombo yeLaserabasebenza kwibhendi ye-1.2μm banezicelo ezizodwa kunyango lwe-photodynamic, ukuxilongwa kwe-biomedical, kunye ne-oxygen sensing. Ukongeza, zinokusetyenziswa njengemithombo yempompo yokuvelisa i-parametric yokukhanya okuphakathi kwe-infrared kunye nokuvelisa ukukhanya okubonakalayo ngokuphindwe kabini. I-Lasers kwi-1.2 μm band iye yaphunyezwa ngeendlela ezahlukeneyoiilaser eziqinileyo, kuqukaiisemiconductor lasers, iilaser zedayimane zeRaman, kunye nefiber lasers. Phakathi kwezi lasers zintathu, i-fiber laser ineenzuzo zesakhiwo esilula, umgangatho olungileyo we-beam kunye nokusebenza okuguquguqukayo, okwenza kube lolona khetho lungcono lokuvelisa i-1.2μm band laser.
Kungekudala, iqela lophando elikhokelwa nguNjingalwazi uPu Zhou e-China linomdla kwi-laser fiber lasers ephezulu kwi-band ye-1.2μm. Ifayibha yamandla ephezulu yangokuiilaserubukhulu becala ytterbium-doped ifayibha lasers kwi 1 μm band, kwaye ubuninzi amandla imveliso kwi 1.2 μm band lilinganiselwe kwinqanaba 10 W. Umsebenzi wabo, enesihloko esithi "Amandla aphezulu kuthatyathwe Raman ifayibha laser kwi 1.2μm waveband," kwaba ipapashwe kwiMida yeOptoelectronics.

Umbono kukusebenzisa i-Raman evuselelweyo isiphumo sokusasazeka kwi-fiber passive ukuvelisa i-laser ephezulu yamandla kwi-1.2μm band. Usasazo lweRaman oluvuselelweyo lulandelelwano lwesithathu lwesiphumo esingenamgca esiguqula iifotoni zibe ngamaza amade.

Abaphandi basebenzise i-Raman ekhuthazwayo yokusasazeka kwi-fiber-doped fiber ukuguqula i-fiber ephezulu ye-ytterbium-doped fiber kwi-1 μm band ukuya kwi-1.2 μm band. Umqondiso weRaman onegunya lokuya kuthi ga kwi-735.8 W ufunyenwe kwi-1252.7 nm, eyona nto iphezulu yamandla ephumayo ye-1.2 μm ye-fiber laser echazwe ngoku.

Umzobo 3: (a) Ubuninzi bemveliso yamandla kunye ne-spectrum yemveliso eqhelekileyo kwiimpawu zamaza ezahlukeneyo. (b) I-spectrum yesiphumo esipheleleyo kuphawu lwamaza ohlukeneyo obude, kwi-dB (Δλ ibhekisa kwi-3 dB yobubanzi bomgca).
