Mea hui fiber optic

Fiber optic bundler mea he fiber optic mea hoʻopili mea, ma o ka fiber precision splicing enehana, no laila, i ka transmitting puluniu puka o ka ikehu ikehu a hiki i ka loa hui 'ana i ka loaʻa pulupulu, a no laila, ma muli o kona wawa ma ka optical ala a me ka. hoemiia ka hopena ma ka pūnaewele.He mea nui ka Fiber combiner i ka ʻōnaehana laser fiber, ʻaʻole i hoʻoholo pololei kona ʻano i ka mana o ka laser fiber a me ka maikaʻi o ka beam, akā he hōʻoia nui no ka hana palekana a paʻa o ka laser.

Hoʻokaʻawale ʻana i nā pūʻulu fiber optic

E like me ka hoʻokaʻawale ʻana o nā hana i hoʻohana ʻia, hiki ke hoʻokaʻawale ʻia nā pūpū fiber optic i ʻelua mau ʻāpana: nā puʻupuʻu mana a me nā puʻupuʻu pump.

(1) ʻO ka hui pū ʻana o ka pauma ka mea nui i ka multi-channel pump photosynthetic beam i kahi puka fiber optical, i hoʻohana nui ʻia e hoʻonui i ka mana pamu.

(2) ʻO ka hui pū ʻana o ka mana ka hoʻohui ʻana i ka beam laser single-mode multi-channel i kahi fiber optical e hoʻopuka, i hoʻohana ʻia e hoʻomaikaʻi i ka mana hoʻopuka o ka laser.

Pumi puʻupuʻu

Mea hui kukui mana

Ma muli o ka hoʻonohonoho ʻana, hiki ke hoʻokaʻawale ʻia nā pūʻulu fiber i ʻelua mau ʻāpana: N × 1 fiber bundlers ʻaʻole i loaʻa i nā mea hōʻailona, ​​a me (N + 1) × 1 fiber bundlers i loaʻa nā fibers hōʻailona.ʻAʻole like me ka N × 1 fiber bundler, ʻo ka fiber optical i waenakonu o ka (N + 1) × 1 fiber bundler he mea hōʻailona.I ka wā o ke kaʻina hana, pono e paʻa a hoʻonohonoho like ʻia nā fibers a puni ka fiber hōʻailona, ​​a hoʻohana ʻia ke kaula hōʻailona ma waena no ka hoʻokomo ʻana i ke kukui hōʻailona.Loaʻa i ka N × 1 beam combiner ka mana beam combiner a me ka pump bundler, ʻo ka hana o ka ʻokoʻa e pili ana i ke ʻano o ka fiber input N-channel, inā ʻo ka fiber N-channel he fiber mode hoʻokahi a i ʻole fiber field mode nui, hiki iā ia ke pili pono i nā lasers N.Hoʻohana ʻia e hoʻonui i ka mana hoʻopuka o ka laser, ʻo ia hoʻi, ka hui pū ʻana o ka mana beam;Inā he multimode fiber ka N-way fiber, ua hoʻopili ʻia ia i nā puna wai N no ka hoʻonui ʻana i ka mana pamu o ka laser, ʻo ia hoʻi, ka hui pū.

▲ N × 1 Puʻupuʻu Fiber
(N+1) × 1 Beam Combiner ʻo ia nā puʻupuʻu pauma, hoʻohana nui ʻia i nā ʻōnaehana hoʻonui fiber.ʻO ka fiber mode hoʻokahi i waenakonu o ka pūpū he fiber hōʻailona no ka hoʻounaʻana i ke kukui hōʻailona, ​​aʻo ka N-channel multimode fiber a puni ia he pulu pulu no ka laweʻana i ke kukui pumped.Hoʻohana mau ʻia kēia pūʻulu i nā hale MOPA.

ʻO nā puʻupuʻu pauma ʻaoʻao a me nā puʻupuʻu pauma hope

ʻO ke kikowaena o ka hui ʻaoʻao ʻaoʻao ʻo ia ka fiber hōʻailona, ​​ʻo ka fiber core he hoʻokahi-mode a i ʻole quasi-single-mode waveguide no ka hoʻouna ʻana i nā lasers, a ʻo ka peripheral eono fibers he mau pulu pulu no ka puhi ʻana i ke kukui.Hoʻonohonoho maikaʻi ʻia nā ʻehiku a hoʻoheheʻe ʻia a hoʻoheheʻe ʻia a hoʻopili ʻia me ka pulupulu lole lua.

▲ ʻO ka puʻupuʻu pauma maka hoʻopau fiber optic puʻupuʻu

'Oko'a ka pu'upu'u 'ao'ao mai ka pu'upu'u pauma no ka huki 'ana o ka pulupulu o ka pu'upu'u 'ao'ao a ho'okomo 'ia i ka enveloppe o ka pulupulu hō'ailona, ​​'a'ole ho'ohehe'e 'ia ka pulu hō'ailona.No laila, ʻoi aku ka maikaʻi o ka lawe ʻana i ka hōʻailona hui pū ʻaoʻao ma mua o ka puʻupuʻu pauma hope ma ke kumu.

Ka hana ʻana i nā mea hui kukui

ʻO ka ʻōnaehana kumu o ka puʻupuʻu mana he ʻekolu mau ʻāpana: fiber input, fusion conical fiber bundle a me ka fiber output.

▲ ʻO ke ʻano kumu o ka puʻupuʻu mana

ʻO ka mea mua, i mea e hoʻopili maikaʻi ʻia ai ka puʻupuʻu fiber me ka pulupulu hoʻopuka ma hope o ka hoʻoheheʻe ʻana a me ka huki ʻana i ka cone, pono e koi ʻia ke ʻano o ke keʻa o ka puʻupuʻu fiber he pōʻai, a ua hoʻonohonoho paʻa ʻia ka pulupulu pulu i kahi. ʻO kekahi ʻano geometric, maʻamau, hoʻonohonoho paʻa ʻia ka fiber ma kahi ʻano hexagonal maikaʻi.I ka wā o ke kaʻina hana, ua hānai mua ʻia ka pūpū fiber input, a laila hoʻoheheʻe ʻia ka pūpū fiber input o ka pūpū a hoʻopaʻa ʻia e hana i kahi pūpū cone fiber, a laila ʻoki ʻia ka pūhaka cone o ka pūpū fiber cone a hoʻopili ʻia me ka puluniu puka.ʻO ka mea hope loa, ua hoʻolālā ʻia kahi pūʻolo kūpono a me ka hoʻolālā wela e hōʻoia i ka hiki ke hana paʻa i ka beam combiner no ka manawa lōʻihi.Hoʻohana pinepine ʻia ke keleawe keleawe a me ka alumini me ka conductivity thermal kiʻekiʻe ma ke ʻano he hale no ka encapsulation a me ka hoʻopau wela, a inā pono, ua hoʻolālā ʻia nā hale hoʻoluʻu wai ma luna o ka encapsulation metala.Hoʻopili ʻia nā laser fiber no ka hoʻokō ʻana i ka pilina o nā mea uila fiber optic.I mea e hiki ai i nā lasers ke hoʻokō i nā kikoʻī mana kiʻekiʻe, he mea nui ka splicing fiber kiʻekiʻe.I ka wā o ka hui ʻana o nā fibers, ʻaʻole hiki ke loaʻa nā poho e hōʻiliʻili i ka māmā a me ka wela i ka wā o ka hana ʻana i ka laser, hiki ke alakaʻi i ka hōʻemi ʻana i ka maikaʻi o ka beam a i ʻole ka pōʻino i nā optics.Hoʻohana ʻo Guanghui Laser i ka ʻenehana hoʻokele wela weld point no ka lanakila ʻana i nā pilikia ʻenehana o ke koena wela o ka mana kiʻekiʻe, a ma o ka hoʻokele piha ʻana i ka simulation simulation optimization a me ka hoʻolālā hoʻoluʻu wai hou, hiki iā ia ke hōʻoia i ka hana paʻa o ka laser.
