Kua whakawhanakehia e tētahi tīma Hainamana tētahi roopu Raman kaha-teitei 1.2μm ka taea te whakarerekēmuka rēseri
Ngā pūtake taiahoKo ngā mea e mahi ana i roto i te roopu 1.2μm he maha ā rātou tono ahurei i roto i te whakaora whakaahua-ā-tinana, te tātaritanga koiora, me te ine hāora. Hei tāpiri, ka taea te whakamahi hei puna papu mō te whakaputanga taurite o te mārama waenga-infrared me te whakaputa mārama kitea mā te whakarea auau. Kua tutukihia ngā taiaho i roto i te roopu 1.2 μm me ngā momo rerekē.ngā taiaho totoka, tae atu kingā taiaho haurua-ira, ngā taiaho Raman taimana, me ngā taiaho muka. I roto i ēnei taiaho e toru, ko ngā painga o te taiaho muka he hanganga māmā, he kounga hihi pai, he ngāwari hoki te mahi, ā, koinei te kōwhiringa pai rawa atu hei whakaputa taiaho roopu 1.2μm.
Nō nā tata nei, kei te hiahia te tīma rangahau i arahina e Ahorangi Pu Zhou i Haina ki ngā taiaho muka mana-teitei i roto i te awhe 1.2μm. Ko te muka mana-teitei o nāianeingā taiahoko te nuinga he ytterbium-doped fiber lasers i roto i te roopu 1 μm, ā, ko te mana putanga mōrahi i roto i te roopu 1.2 μm e herea ana ki te taumata o te 10 W. Ko tā rātou mahi, ko "High power tunable Raman fiber laser at 1.2μm waveband," i whakaputaina i roto i ngā Frontiers ofNgā taputapu hikohiko.
PIK. 1: (a) Tatūnga whakamātautau o tētahi whakakaha muka Raman ka taea te whakarerekē mana-teitei me te (b) taiaho purapura muka Raman matapōkere ka taea te whakarerekē i te roopu 1.2 μm.

P3: e tohu ana i te tauranga 3. Puna: Zhang Yang et al., Taiaho muka Raman ka taea te whakarerekē mana-teitei i te roopu ngaru 1.2μm, Frontiers of Optoelectronics (2024).
Ko te whakaaro he whakamahi i te pānga marara Raman whakaohooho i roto i te muka kore mahi hei whakaputa i te taiaho mana-teitei i roto i te roopu 1.2μm. Ko te marara Raman whakaohooho he pānga kore-raina tuatoru e huri ana i ngā photon ki ngā roangaru roa ake.
Pikitia 2: Ngā hihi putanga RFL matapōkere ka taea te whakarerekē i (a) 1065-1074 nm me (b) ngā roangaru papu 1077 nm (e pā ana te Δλ ki te 3 dB whānui raina). Puna: Zhang Yang et al., Taiaho muka Raman ka taea te whakarerekē mana teitei i te awhe ngaru 1.2μm, Frontiers of Optoelectronics (2024).
I whakamahia e ngā kairangahau te pānga marara Raman whakaohooho i roto i te muka kua tāpirihia ki te phosphorus hei huri i te muka kua tāpirihia ki te ytterbium mana-teitei i te roopu 1 μm ki te roopu 1.2 μm. I whiwhihia he tohu Raman me te mana tae atu ki te 735.8 W i te 1252.7 nm, koinei te mana putanga teitei rawa atu o te taiaho muka roopu 1.2 μm kua pūrongohia tae noa ki tēnei wā.
Pikitia 3: (a) Te mana putanga mōrahi me te whānuitanga putanga kua whakatauritea i ngā roangaru tohu rerekē. (b) Te whānuitanga putanga katoa i ngā roangaru tohu rerekē, i roto i te dB (e pā ana te Δλ ki te 3 dB te whānui raina).
