Iqela laseTshayina liphuhlise iRaman enamandla amakhulu enokuguqulwa ibe yi-1.2μmi-laser yefayibha

Imithombo yelaserEzisebenza kwi-1.2μm band zinezicelo ezikhethekileyo kunyango lwe-photodynamic, ukuxilongwa kwe-biomedical, kunye nokubona i-oxygen. Ukongeza, zingasetyenziswa njengemithombo yepompo yokuvelisa ukukhanya kwe-mid-infrared kunye nokuvelisa ukukhanya okubonakalayo ngokuphindaphindwa kabini. Iilaser kwi-1.2 μm band zifezekisiwe ngeendlela ezahlukeneyo.iileyiza zesimo esiqinileyo, kuqukaiileyiza ze-semiconductor, iilaser zedayimani zeRaman, kunye neelaser zefayibha. Phakathi kwezi laser zintathu, ilaser yefayibha ineenzuzo zesakhiwo esilula, umgangatho olungileyo wemitha kunye nokusebenza okuguquguqukayo, nto leyo eyenza kube lolona khetho lufanelekileyo lokuvelisa ilaser yebhendi ye-1.2μm.
Kutshanje, iqela lophando elikhokelwa nguNjingalwazi uPu Zhou eTshayina linomdla kwi-laser yefayibha enamandla aphezulu kwibhendi ye-1.2μm. Ifayibha enamandla aphezulu yangokuiileyizaikakhulu zii-laser zefayibha ezifakwe i-ytterbium kwi-1 μm band, kwaye amandla aphezulu okukhupha kwi-1.2 μm band anqunyelwe kwinqanaba le-10 W. Umsebenzi wabo, onesihloko esithi “I-laser yefayibha yeRaman enamandla aphezulu kwi-1.2 μm waveband,” yapapashwa kwiFrontiers ofI-Optoelectronics.

UMZOBO 1: (a) Useto lovavanyo lwe-Raman fiber amplifier enamandla aphezulu kunye (b) i-Raman fiber seed laser engaguqukiyo kwi-1.2 μm band. I-PDF: i-phosphorus-doped fiber; I-QBH: I-Quartz bulk; I-WDM: I-Wavelength division multiplexer; I-SFS: umthombo wokukhanya we-fiber ye-superfluorescent; I-P1: i-port 1; I-P2: i-port 2. I-P3: ibonisa i-port 3. Umthombo: UZhang Yang et al., I-Raman fiber laser enamandla aphezulu kwi-1.2μm waveband, I-Frontiers of Optoelectronics (2024).
Ingcinga kukusebenzisa isiphumo sokusasazeka kweRaman esivuselelweyo kwifayibha engasebenziyo ukuvelisa i-laser enamandla aphezulu kwibhendi ye-1.2μm. Ukusasazeka kweRaman okuvuselelweyo sisiphumo esingangqalanga sesithathu esiguqula ii-photons zibe zii-wavelengths ezinde.

Umfanekiso 2: Iispectra zemveliso ze-RFL ezingacwangciswanga ezilungisekayo kwi-(a) 1065-1074 nm kunye (b) ii-wavelengths zepompo ze-1077 nm (Δλ ibhekisa kububanzi bomgca obuyi-3 dB). Umthombo: Zhang Yang et al., I-laser yefayibha yeRaman enamandla aphezulu elungisekayo kwi-waveband ye-1.2μm, iFrontiers of Optoelectronics (2024).
Abaphandi basebenzise isiphumo sokusasazeka kweRaman esivuselelweyo kwifayibha efakwe i-phosphorus ukuguqula ifayibha efakwe i-ytterbium enamandla aphezulu kwibhendi ye-1 μm ibe yibhendi ye-1.2 μm. Isignali yeRaman enamandla afikelela kwi-735.8 W ifunyenwe kwi-1252.7 nm, eli ligunya eliphezulu lokukhupha i-laser yefayibha yebhendi ye-1.2 μm exeliweyo ukuza kuthi ga ngoku.

Umfanekiso 3: (a) Amandla aphezulu okukhupha kunye ne-spectrum yemveliso eqhelekileyo kwii-wavelengths ezahlukeneyo zesignali. (b) I-spectrum yemveliso epheleleyo kwii-wavelengths ezahlukeneyo zesignali, kwi-dB (Δλ ibhekisa kububanzi bomgca obuyi-3 dB).
