ʻO nā lasers, kahi pōhaku kihi o ka ʻenehana hou, he mea hoihoi e like me ka paʻakikī. Aia i loko o ko lākou puʻuwai kahi symphony o nā ʻāpana e hana like ana e hana i ka mālamalama coherent, amplified. Hoʻopili kēia blog i ka paʻakikī o kēia mau ʻāpana, i kākoʻo ʻia e nā loina ʻepekema a me nā hoʻohālikelike, e hāʻawi i kahi ʻike hohonu o ka ʻenehana laser.
Nā ʻike kiʻekiʻe i nā ʻāpana Pūnaehana Laser: He Manaʻo ʻenehana no nā ʻoihana
| ʻāpana | Hana | Nā laʻana |
| Loaʻa i ka Medium | ʻO ka medium gain ka mea i loko o kahi laser i hoʻohana ʻia no ka hoʻonui ʻana i ka mālamalama. Hoʻomaʻamaʻa ia i ka hoʻonui māmā ma o ke kaʻina o ka hoʻohuli ʻana o ka heluna kanaka a me ka hoʻoulu ʻia ʻana. ʻO ke koho o ka gain medium e hoʻoholo i nā ʻano radiation o ka laser. | Nā Laser Mokuʻāina Paʻa: e laʻa, Nd:YAG (Neodymium-doped Yttrium Aluminum Garnet), hoʻohana ʻia i nā noi olakino a me nā ʻoihana.Nā Laser Gas: laʻa, CO2 lasers, hoʻohana ʻia no ka ʻoki ʻana a me ka wili.Nā Laser Semiconductor:laʻa, laser diodes, hoʻohana ʻia i ke kamaʻilio fiber optics a me nā kuhikuhi laser. |
| Punawai | Hāʻawi ka puna wai i ka ikehu i ka mea e loaʻa ai ka hoʻololi ʻana o ka heluna kanaka (ke kumu ikehu no ka hoʻohuli ʻana o ka heluna kanaka), hiki i ka hana laser. | ʻO ka Pumi ʻOpika: Ke hoʻohana ʻana i nā kumu kukui ikaika e like me nā kukui uila e puhi i nā lasers solid-state.Pahu Uila: Hoʻohauʻoli i ke kinoea i nā laser gas ma o ke au uila.Semiconductor Pumping: Ke hoʻohana ʻana i nā diodes laser e paʻi i ka mīkini paʻa. |
| ʻŌnaehana Optical | ʻO ka lua optical, ʻelua mau aniani, e hōʻike ana i ka mālamalama e hoʻonui i ka lōʻihi o ke ala o ka mālamalama i loko o ka mea loaʻa, a laila e hoʻonui ai i ka hoʻonui māmā. Hāʻawi ia i kahi hana pane no ka hoʻonui ʻana i ka laser, ke koho ʻana i nā hiʻohiʻona spectral a me spatial o ka mālamalama. | Papa-Planar Cavity: Hoʻohana ʻia i ka noiʻi keʻena hana, hana maʻalahi.ʻŌwaʻa Planar-Concave: He mea maʻamau i nā lasers ʻoihana, hāʻawi i nā kukui kiʻekiʻe. apo apo: Hoʻohana ʻia i nā hoʻolālā kikoʻī o nā laser ring, e like me nā lasers ring gas. |
ʻO ka Gain Medium: He Nexus o Quantum Mechanics a me Optical Engineering
Quantum Dynamics ma ka Gain Medium
ʻO ka medium gain kahi e kū ai ke kaʻina kumu o ka hoʻonui ʻana i ka māmā, kahi mea i hoʻokumu ʻia i ka mīkini quantum. Hoʻoponopono ʻia ka pilina ma waena o nā mokuʻāina ikehu a me nā ʻāpana i loko o ke kikowaena e nā loina o ka hoʻoulu ʻia a me ka hoʻohuli ʻana o ka lehulehu. ʻO ka pilina koʻikoʻi ma waena o ka ikaika māmā (I), ka ikaika mua (I0), ka ʻāpana keʻa hoʻololi (σ21), a me nā helu ʻāpana ma nā pae ikehu ʻelua (N2 a me N1) i wehewehe ʻia e ka hoohalike I = I0e^ (σ21(N2-N1)L). ʻO ka loaʻa ʻana o ka huli ʻana o ka heluna kanaka, kahi o N2 > N1, he mea nui ia no ka hoʻonui ʻana a he pōhaku kihi ia o ka physics laser [1].
Nā Pūnaehana Papa ʻEkolu vs
Ma nā hoʻolālā laser kūpono, hoʻohana mau ʻia nā ʻōnaehana ʻekolu-level a me ʻehā. ʻO nā ʻōnaehana pae ʻekolu, ʻoiai ʻoi aku ka maʻalahi, e koi i ka ikehu hou aʻe e hoʻokō ai i ka hoʻololi ʻana o ka heluna kanaka e like me ka pae laser haʻahaʻa ʻo ia ka ʻāina. ʻO nā ʻōnaehana pae ʻehā, ma ka ʻaoʻao ʻē aʻe, hāʻawi i kahi ala ʻoi aku ka maikaʻi o ka hoʻohuli ʻana i ka heluna kanaka ma muli o ka wikiwiki o ka palaho non-radiative mai ke kiʻekiʻe o ka ikehu kiʻekiʻe, e hoʻonui iā lākou i nā noi laser hou.2].
Is ʻErbium-doped anianihe mea waiwai?
ʻAe, ʻo ke aniani erbium-doped ʻoiaʻiʻo ke ʻano o ka loaʻa ʻana i hoʻohana ʻia i nā ʻōnaehana laser. Ma kēia pōʻaiapili, pili ka "doping" i ke kaʻina hana o ka hoʻohui ʻana i kekahi nui o nā ion erbium (Er³⁺) i ke aniani. ʻO ka Erbium kahi mea honua laha ʻole, ke hoʻokomo ʻia i loko o kahi pūʻali aniani, hiki ke hoʻonui pono i ka mālamalama ma o ka hoʻoulu ʻia ʻana, kahi kaʻina kumu i ka hana laser.
He mea kaulana loa ke aniani Erbium-doped no kona hoʻohana ʻana i nā laser fiber a me nā mea hoʻonui fiber, ʻoi aku hoʻi i ka ʻoihana kelepona. He kūpono ia no kēia mau noi no ka mea e hoʻonui maikaʻi ʻo ia i ka mālamalama ma nā lōʻihi hawewe ma kahi o 1550 nm, ʻo ia ka lōʻihi hawewe koʻikoʻi no nā kamaʻilio fiber optical ma muli o kona haʻahaʻa haʻahaʻa i nā fiber silica maʻamau.
ʻO kaerbiumhoʻopaʻa nā ion i ke kukui pamu (pinepine mai adiode laser) a ke hauʻoli nei i nā mokuʻāina ikehu kiʻekiʻe. Ke hoʻi lākou i kahi kūlana ikehu haʻahaʻa, hoʻopuka lākou i nā kiʻi kiʻi ma ka lōʻihi o ka nalu lasing, e hāʻawi ana i ke kaʻina laser. Hana kēia i ke aniani erbium-doped i mea hoʻohana pono a hoʻohana nui ʻia i nā hoʻolālā laser a me ka amplifier.

Mechanisms Pumping: ʻO ka ikaika hoʻokele ma hope o nā lasers
Nā ʻano ala like ʻole no ka loaʻa ʻana o ka hoʻohuli ʻana o ka lehulehu
He mea koʻikoʻi ke koho ʻana i ka mīkini pahū i ka hoʻolālā laser, e hoʻohuli ana i nā mea āpau mai ka pono a hiki i ka lōʻihi o ka hawewe. ʻO ka pumping Optical, me ka hoʻohana ʻana i nā kumu kukui o waho e like me nā kukui uila a i ʻole nā lasers ʻē aʻe, he mea maʻamau i nā lasers solid-state a me ka wai. Hoʻohana pinepine ʻia nā ʻano hoʻokuʻu uila i nā laser gas, aʻo nā laser semiconductor e hoʻohana pinepine i ka injection electron. ʻO ka maikaʻi o kēia mau mīkini pahū, ʻo ia hoʻi i nā lasers solid-state diode-pumped, he mea nui ia o ka noiʻi hou ʻana, e hāʻawi ana i ka ʻoi aku ka maikaʻi a me ka compactness[3].
Noʻonoʻo ʻenehana i ka maikaʻi o ka Pumping
ʻO ka maikaʻi o ke kaʻina hana pumping he mea koʻikoʻi o ka hoʻolālā laser, ka hopena o ka hana holoʻokoʻa a me ke kūpono o ka noi. I nā lasers solid-state, hiki i ke koho ʻana ma waena o nā kukui uila a me nā diodes laser ma ke ʻano he puna puna hiki ke hoʻopilikia nui i ka pono o ka ʻōnaehana, ka ukana wela, a me ka maikaʻi o ka beam. ʻO ka hoʻomohala ʻana i nā diodes laser mana kiʻekiʻe, ua hoʻololi i nā ʻōnaehana laser DPSS, e hiki ai i nā hoʻolālā paʻa a maikaʻi loa.4].
ʻO ka ʻĀpana Optical: ʻEnekinia i ka Laser Beam
Hoʻolālā Cavity: He Kanawai Kaulike o ka Physics and Engineering
ʻO ka lua opua, a i ʻole resonator, ʻaʻole ia he ʻāpana passive akā he mea komo ikaika i ka hana ʻana i ka kukuna laser. ʻO ka hoʻolālā ʻana o ka lua, me ka curvature a me ka alignment o nā aniani, he hana koʻikoʻi i ka hoʻoholo ʻana i ke kūpaʻa, ke ʻano hana, a me ka puka o ka laser. Pono e hoʻolālā ʻia ka lua e hoʻomaikaʻi i ka loaʻa ʻana o ka optical a ʻo ka hōʻemi ʻana i nā poho, kahi paʻakikī e hoʻohui i ka ʻenehana optical me nā optics nalu.5.
Nā Kūlana Oscillation a me ke koho ʻana i ke ʻano
No ka hoʻomaka ʻana o ka laser oscillation, ʻoi aku ka nui o ka loaʻa i hāʻawi ʻia e ka mea waena ma mua o nā poho i loko o ka lua. ʻO kēia kūlana, i hui pū ʻia me ke koi no ka superposition nalu coherent, e ʻōlelo ana e kākoʻo ʻia kekahi mau mode longitudinal. Hoʻopili ʻia ke ʻano spacing a me ke ʻano holoʻokoʻa holoʻokoʻa e ka lōʻihi kino o ka lua a me ka index refractive o ka medium gain[6].
Ka hopena
Hoʻopili ka hoʻolālā a me ka hana ʻana o nā ʻōnaehana laser i kahi ākea ākea o ka physics a me nā loina ʻenekinia. Mai ka quantum mechanics e hoʻomalu ana i ka loaʻa ʻana a hiki i ka ʻenehana paʻakikī o ka lua optical, he mea koʻikoʻi kēlā me kēia ʻāpana o ka ʻōnaehana laser i kāna hana holoʻokoʻa. Ua hāʻawi kēia ʻatikala i kahi ʻike i ka honua paʻakikī o ka ʻenehana laser, e hāʻawi ana i nā ʻike e pili ana i ka ʻike holomua o nā polopeka a me nā ʻenekini optical i ke kula.
