ʻO nā laser fiber ma ke kahua o ka launa fiber optical

ʻO kaLaser puluniue pili ana i ka laser e hoʻohana ana i nā fiber glass-doped earth-doped ma ke ʻano he mea waiwai. Hiki ke hoʻomohala ʻia nā laser fiber ma muli o nā amplifiers fiber, a ʻo kā lākou kumu hana: e lawe i ka laser fiber longitudinally pumped i laʻana. Hoʻonoho ʻia kahi ʻāpana o ka fiber doped me nā ion metala honua ʻelua ma waena o nā aniani ʻelua me ka noʻonoʻo i koho ʻia. Hoʻopili ka ipu kukui i loko o ka fiber mai ke aniani hema. Hoʻouna ka aniani hema i nā kukui pauma a hōʻike i ka laser holoʻokoʻa, i mea e hoʻohana pono ai i ke kukui pamu a pale aku i ke kukui pahū mai ke kani ʻana a me ka hoʻoulu ʻana i ke kukui puka ʻole. Hiki i ka endoscope kūpono ke hele i ka ʻāpana laser i mea e hana ai i ka manaʻo o ka kukuna laser a loaʻa ka hopena laser. Hoʻopili ʻia nā kiʻi kiʻi ma ka lōʻihi o ka hawewe pauma e ka mea waena, e hana ana i ka hoʻololi ʻana i ka helu ion, a hope loa e hoʻoulu i ka hoʻokuʻu ʻia i loko o ka doped fiber medium e hoʻopuka i ka laser.

ʻO nā hiʻohiʻona o nā laser fiber: ʻoi aku ka maikaʻi o ka hoʻohui ʻana no ka mea ʻo ke ʻano laser ponoʻī ke ala alakaʻi nalu. ʻO ka hoʻololi hoʻololi kiʻekiʻe, ka paepae haʻahaʻa a me ka hopena wela maikaʻi; Loaʻa iā ia kahi laula hoʻonohonoho ākea, ka hoʻopuehu maikaʻi a me ke kūpaʻa. Hiki ke hoʻomaopopo ʻia nā laser fiber ma ke ʻano he mea hoʻololi i ka hawewe lōʻihi, ʻo ia hoʻi, ka hoʻohuli ʻana i ka lōʻihi o ka nalu o ke kukui pahū i ka lōʻihi o ka nalu lasing o nā ion honua laha ʻole. ʻO kēia hawewe lasing ka pololei o ka hawewe māmā puka o ka laser fiber. ʻAʻole ia e hoʻomalu ʻia e ka lōʻihi o ka hawewe pauma a ua hoʻoholo ʻia e nā mea doping honua laha i loko o ka mea. No laila, hiki ke hoʻohana ʻia nā laser semiconductor o nā hawewe pōkole ʻokoʻa a me ka mana kiʻekiʻe e pili ana i ka spectra absorption o nā ion honua laha ʻole e like me nā puna wai e loaʻa ai nā hopena laser o nā nalu like ʻole.

Hoʻohālikelike laser fiber: Nui nā ʻano o nā laser fiber. E like me ka loaʻa ʻana, hiki ke hoʻokaʻawale ʻia lākou e like me: rare earth doped fiber lasers, nonlinear effect fiber lasers, single crystal fiber lasers, a me plastic fiber lasers. E like me ka hoʻolālā fiber, hiki ke hoʻokaʻawale ʻia lākou i: nā laser fiber-clad a me nā laser fiber-clad pālua. Wahi a nā mea doped, hiki ke hoʻokaʻawale ʻia i loko o nā ʻano he ʻumi e like me ka erbium, neodymium, praseodymium, etc. E like me ke ʻano o ka pumping, hiki ke hoʻokaʻawale ʻia e like me: optical fiber end face pumping, micro prism side optical coupling pumping, ring pumping, etc. "8" shaped cavity lasers, etc. E like me ke ʻano hana, hiki ke hoʻokaʻawale ʻia lākou ma ke ʻano: pulsed optical fiber a me ka laser mau, a me nā mea ʻē aʻe.nā laser mana kiʻekiʻe, nā lasers puʻupuʻu pōkole, anā laser hiki ke hoʻokō ʻiae puka mai ana kekahi ma hope o kekahi. A laila, e hoʻomau ka hoʻomohala ʻana o nā laser fiber i nā kuhikuhi o ka mana hoʻopuka kiʻekiʻe, ʻoi aku ka maikaʻi o ka beam, a me nā kiʻekiʻe pulse kiʻekiʻe.
