ʻOki laser fiber a me ka Lapaʻau

ʻO ka ʻoki laser fiber a me ka lāʻau lapaʻau, ʻo ka mīkini ʻoki laser fiber doped fiber iā ia iho ma ke ʻano he mea hana, a me ka mīkini ʻoki laser fiber ponoʻī, akā ke pāʻani nei hoʻi i ke kuleana o ke alakaʻi ʻana i ka laser solid-state.ʻO Resonator, aia i ka mea hana, puna puna ʻekolu ʻāpana kumu.I nā makahiki i hala iho nei, ʻo nā laser fiber i nā ʻoihana ʻoihana i ka hoʻohui ʻana i kahi ākea o nā noi, a me ka hoʻonui ʻana i ka kaulana i ka lāʻau lapaʻau.

ʻO ka Fiber Technology Center, University of Sydney, Australia (OFT C) o Stuart Jackson i ʻōlelo ʻia: "ʻO ka mīkini ʻoki laser fiber no nā noi ʻokiʻoki, he mea nui ia e hoʻopaʻa i nā lasers, ka liʻiliʻi o ka mālama ʻana, ʻoi aku ka maikaʻi o ka maikaʻi kiʻekiʻe a me nā waiwai wela o ka fiber laser.no ka mea ke hoʻohana nei lākou i kahi diode-pumped, no laila ua paʻa loa.ʻOi aku ka maikaʻi o ke ʻano o ka fiber ma mua o ka mea laser solid-state no ka mea ua maʻalahi ia i ka pono o ka fiber transmission hou, a laila e hōʻemi ana i ke kumukūʻai a hōʻemi i ka Complexity o ka ʻōnaehana".

ʻO ka mīkini ʻoki laser fiber i ka makahiki 1963 e Elias Spritzer i hana ʻia.Ma mua o ke komo ʻana i ka hoʻohana pāʻoihana, ma hope o ʻelua mau makahiki o ke kūkulu ʻana.I ka wā mua, hoʻohana ʻia ka hoʻohana ʻana i ka laser diode hoʻokahi-mode, ʻo ka radiation he ʻumi milliliters wale nō.Akā he nui nā mea hoʻohana i ka nani no ko lākou waiwai kiʻekiʻe, hiki iā ia ke hana i ka hana hoʻomau hoʻokahi o nā ion honua laha, ʻaʻole hiki ke hoʻokō ʻia ka laser kristal.1990, fiber lasers e hoʻokō i ka leap-watt puka pae, a laila, hōʻike i ka erbium-doped puluniu laser puka mana i 4 W, keia hooulu ana i keia la ke ike nei makou i ka mana o 10 W a kiekie ae hookahi-mode fiber lasers kumu.

I ka mīkini ʻokiʻoki fiber laser, ʻo ka fiber ponoʻī e hana ma ke ʻano he resonant cavity.Loaʻa kēia mau mea hana i kahi erbium doped single-mode core ytterbium (a i ʻole nā ​​hui pū ʻana o ia mea), a i ʻole kahi mea honua laha.Hoʻohui ʻia ka ikehu mai ke kumu kukui paʻa, i ka uhi ʻana o ka fiber, a laila i loko o ke kumu, hana ka paila i nā ʻātoma pant.Ma ke kahua lapaʻau, ʻo ka lōʻihi o ka nalu e pono ai: 1.3μm band no ke kiʻi kiʻi, 1.5μm (kiʻekiʻe hoʻoheheʻe wai) -4μm no ka ʻoki ʻana, mai ka mana o ka milliliters a ʻoi aku ma mua o 100 W.

Ua ʻōlelo ʻo Jackson: "ʻO ka hoʻohana ʻana i nā lasers CW, nā noi biomedical, ʻoi aku ka nui o nā lasers CW mana kiʻekiʻe, hiki ke pōmaikaʻi mai ka mīkini ʻoki laser fiber e kahi mīkini ʻoki laser fiber e hāʻawi i ka pono kiʻekiʻe, ākea ka laulā, a me ka hopena holoʻokoʻa.ʻOi aku ka maikaʻi o ka lāʻau mana, ʻoi aku ka maikaʻi;no laila ke hoʻomau nei ka hoʻonui ʻana o ka fiber laser i nā noi olakino.“
