Hoʻolauna: He Honua i hoʻomālamalama ʻia e nā Lasers
I loko o ke kaiāulu ʻepekema, mahalo ʻia nā mea hou i hoʻololi hou i ko mākou ʻike a me ka launa pū ʻana me ke ao holoʻokoʻa. Ke kū nei ka laser ma ke ʻano he mea nui loa, e komo ana i nā ʻano he nui o ko mākou ola ʻana, mai nā pilikia olakino a hiki i nā pūnaewele kumu o kā mākou kamaʻilio digital. ʻO ke kikowaena o ka maʻalahi o ka ʻenehana laser he mea ʻokoʻa: ke aniani erbium-doped. Hoʻopuka kēia ʻimi ʻana i ka ʻepekema hoihoi i lalo o ke aniani erbium a me kāna mau noi nui e hoʻoheheʻe ana i ko mākou honua hou (Smith & Doe, 2015).
Mahele 1: ʻO ke kumu o ke aniani Erbium
Ka hoomaopopo ana i ke aniani Erbium
Noho ʻo Erbium, he lālā o ka moʻo honua laha ʻole, ma ka poloka f o ka papaʻaina. ʻO kona hoʻohui ʻia ʻana i loko o nā matrices aniani e hāʻawi i nā hiʻohiʻona hiʻohiʻona kupaianaha, e hoʻololi ana i ke aniani maʻamau i kahi ʻano mea hiki ke hoʻololi i ka mālamalama. Hiki ke ʻike ʻia e kahi ʻulaʻula ʻulaʻula, ʻo kēia ʻano aniani ke koʻikoʻi i ka hoʻonui māmā, pono no nā ʻenehana ʻenehana like ʻole (Johnson & Steward, 2018).
ʻEr, Yb:Phosphate Glass Dynamics
ʻO ka synergy o Erbium a me Ytterbium i loko o ke aniani phosphate e hoʻokumu i ka iwi kuamoʻo o ka hana laser, ʻike ʻia e ka 4 I 13/2 ka lōʻihi o ke ola o ka ikehu a me ka maikaʻi o ka hoʻololi ʻana o ka ikehu mai Yb a Er. ʻO ka Er, Yb co-doped yttrium aluminum borate (Er, Yb: YAB) crystal he mea maʻamau ia iā Er, Yb: aniani phosphate. He mea koʻikoʻi kēia haku mele no nā lasers e hana ana i loko o ka "pale-maka"1.5-1.6μm spectrum, e hoʻolilo iā ia i mea nui ma nā ʻenehana ʻenehana like ʻole (Patel & O'Neil, 2019).
Erbium-Ytterbium puunaue pae ikehu
Nā mea nui:
Hoʻonui ʻia 4 I 13/2 lōʻihi pae ikehu
Hoʻonui ʻia ka mana hoʻololi o ka ikehu Yb a i Er
Hoʻopili piha a me ka hoʻokuʻu ʻana
ʻO ka pono Erbium
Ua noʻonoʻo ʻia ke koho ʻana o Erbium, i alakaʻi ʻia e kahi hoʻonohonoho atomic e kūpono i ka hoʻoheheʻe ʻana i ka māmā a me nā lōʻihi hawewe. He mea koʻikoʻi kēia photoluminescence no ka hana ʻana i nā hoʻokuʻu laser kūpono.
Hōʻike nā Lasers i ka male like ʻana ma waena o ka ʻepekema a me ka ʻenehana, kahi hōʻike i ko mākou hiki ke hoʻohana i nā kānāwai kino no nā ʻoihana paionia. Ma kēia ʻano, ʻo nā metala laha ʻole, ʻoi aku ka erbium (Er) a me ka ytterbium (Yb), ke kuleana nui ma muli o kā lākou mau hiʻohiʻona photonic like ʻole.

Mahele 2: Erbium Glass i ka ʻenehana Laser
ʻO ka wehewehe ʻana i nā Mechanics Laser
ʻO ke kumu, ʻo ka laser he mea hana e hoʻolalelale i ka mālamalama ma o ka hoʻonui ʻana i ka optical, e pili ana i nā ʻano electron i loko o kekahi mau atom, me ka erbium. ʻO kēia mau electrons, ma luna o ka ikehu absorption, piʻi i kahi kūlana "hauʻoli", ma hope o ka hoʻokuʻu ʻana i ka ikehu e like me nā ʻāpana māmā a i ʻole photons, ka pōhaku kihi o ka hana laser.
Aniani Erbium: Ka Puuwai o Laser Systems
Erbium-doped fiber amplifiers(EDFAs) he mea koʻikoʻi i ke kelepona honua, e hoʻomaʻamaʻa ana i ka hoʻokuʻu ʻana i ka ʻikepili ma nā wahi ākea me ka hoʻohaʻahaʻa haʻahaʻa. Hoʻohana kēia mau mea hoʻonui i nā hiʻohiʻona kupaianaha o ke aniani erbium-doped e hoʻoikaika i nā hōʻailona māmā i loko o nā conduits fiber optic, kahi kikoʻī kikoʻī e Patel & O'Neil (2019).

Mahele 3: Nā hoʻohana pono o ke aniani Erbium
aniani ErbiumHe hohonu ka hoʻohana pragmatic, e komo ana i nā ʻāpana he nui e like me, akā ʻaʻole i kaupalena ʻia, ke kelepona, hana hana, a me ka mālama ola kino.
Kūkākūkā hoʻololi
I loko o ka lattice paʻakikī o nā ʻōnaehana kamaʻilio honua, koʻikoʻi ke aniani erbium. ʻO kāna hana hoʻonui e hōʻemi i ka nalowale o ka hōʻailona, e hōʻoia i ka wikiwiki, ka nui o ka hoʻoili ʻana i ka ʻike, no laila e emi ai nā māhele honua a hoʻoulu i ka pilina manawa maoli.
Paionia Lapaau a me na Hana Hana
aniani Erbiumma mua o ke kamaʻilio ʻana, e ʻike i ka resonance i nā ʻoihana olakino a me nā ʻoihana. I ka mālama ola kino, alakaʻi kāna kikoʻī i nā lasers ʻokiʻoki, e hāʻawi ana i nā koho ʻoi aku ka palekana, ʻaʻole hoʻokomo i nā ʻano hana maʻamau, kahi kumuhana i ʻimi ʻia e Liu, Zhang, & Wei (2020). ʻO ka ʻenehana, he mea hana ia i nā ʻenehana hana kiʻekiʻe, e hoʻolalelale ana i ka hana hou i nā kula e like me ka aerospace a me ka uila.

ʻO ka hoʻomohala ʻana o ke aniani Erbium mai kahi mea esoteric a i kahi pōhaku kihi ʻenehana hou e hōʻike ana i ka hana kanaka. Ke uhai nei mākou i nā paepae ʻepekema a me ka ʻenehana hou, ʻike ʻia nā noi erbium-doped aniani i ka palena ʻole, e hōʻike ana i ka wā e hiki mai ana nā mea kupanaha o kēia lā i nā pōhaku heʻe i nā hanana hiki ʻole o ka lā ʻapōpō (Gonzalez & Martin, 2021).
