Kua whakawhanakehia e tetahi roopu Hainamana tetahi roopu 1.2μm te kaha teitei Ramantaiaho muka
Nga puna taiahoe mahi ana i roto i te roopu 1.2μm he tono ahurei i roto i te whakamaaramatanga whakaahua, te tātaritanga koiora, me te tirotiro hāora.I tua atu, ka taea te whakamahi hei puna papu mo te whakangao parametric o te rama-waenganui-a-whare me te whakaputa rama kitea ma te rearua.Ko nga lasers i roto i te roopu 1.2 μm kua tutuki me te rerekelasers āhua totoka, tae atu kilasers semiconductor, taimana taimana Raman, me taiaho muka.I roto i enei lasers e toru, te muka taiaho he nga painga o te hanganga ohie, te kounga kurupae pai me te mahi ngāwari, e hanga ana e ia te whiriwhiri pai ki te whakaputa taiaho ropu 1.2μm.
I tata nei, ko te roopu rangahau e arahina ana e te Ahorangi Pu Zhou i Haina e hiahia ana ki nga laser fiber mana teitei i roto i te roopu 1.2μm.Ko te muka mana teitei o naianeitaiahoKo te nuinga o nga lasers muka ytterbium-doped i roto i te roopu 1 μm, a ko te kaha o te kaha whakaputa i roto i te roopu 1.2 μm he iti ki te taumata o te 10 W. Ko ta raatau mahi, ko te "High power tunable Raman fiber laser at 1.2μm waveband," ko whakaputaina i Frontiers oOptoelectronics.

Ko te whakaaro ko te whakamahi i te whakaihiihi a Raman scattering effect i roto i te muka hāngū ki te whakaputa i te taiaho mana nui i roto i te roopu 1.2μm.Ko te whakamararatanga Raman whakahihiri he huanga-kore rarangi tuatoru e huri ana i nga whakaahua ki nga roangaru roa.

I whakamahia e nga kairangahau te whakaihiihi a Raman marara i roto i te muka phosphorus-doped ki te huri i te muka ytterbium-doped teitei i te roopu 1 μm ki te roopu 1.2 μm.He tohu Raman me te kaha ki runga ki te 735.8 W i whiwhi i te 1252.7 nm, ko te mana whakaputa teitei o te 1.2 μm band fiber laser i korerotia ki tenei ra.
