Pūtaiao Iti: Ngā Mātāpono me ngā Whakamahinga Tukanga mō te Whakarewatanga Taiaho
Ngā Taumata Pūngao
He mea tito te matū i ngā ngota, ā, he karihi me ngā irahiko ngā ngota. Ka porowhita ngā irahiko i te karihi. Kāore te kaha o ngā irahiko i roto i te ngota i te mea tūpono noa.
E whakaatu ana te hangarau matūriki, e whakaahua ana i te ao moroiti, kei te noho ngā irahiko i ngā taumata pūngao pumau. He rerekē ngā taumata pūngao e rite ana ki ngā pūngao irahiko rerekē: he nui ake te pūngao o ngā porowhita e tawhiti atu ana i te karihi.
Hei tāpiritanga, ka taea e ia porowhita te pupuri i te maha o ngā irahiko. Hei tauira, ko te porowhita iti rawa (e tata ana ki te karihi) ka taea te pupuri i te 2 irahiko, ko ngā porowhita teitei ake ka taea te pupuri i te 8 irahiko, me ērā atu.
Whakawhiti
Ka taea e ngā irahiko te neke mai i tētahi taumata pūngao ki tētahi atu mā te mimiti, te tuku rānei i te pūngao.
Hei tauira, ina mimiti te irahiko i te photon, ka peke pea mai i te taumata pūngao iti ki te taumata teitei ake. Waihoki, ka taea e te irahiko i te taumata pūngao teitei ake te heke ki te taumata iti ake mā te tuku i te photon.
I roto i ēnei tukanga, ko te kaha o te photon i mimitihia, i tukuna rānei, he ōrite tonu ki te rerekētanga kaha i waenga i ngā taumata e rua. Nā te mea ko te kaha photon te mea e whakatau ana i te roangaru o te mārama, he pumau te tae o te mārama i mimitihia, i tukuna rānei.
Te Mātāpono o te Whakaputa Taiaho
Ngongo Whakaohooho
Ka puta te mimiti whakaohooho ina mimiti ngā ngota i roto i te āhua iti-pūngao i te hihi o waho, ā, ka neke ki te āhua teitei-pūngao. Ka taea e ngā irahiko te peke mai i ngā taumata pūngao iti ki te teitei mā te mimiti i ngā photon.
Tukunga Whakaohooho
Ko te tikanga o te tukunga whakaohooho ko ngā irahiko i te taumata pūngao teitei, i raro i te "whakaohooho" te "whakaohooho" rānei o te photon, ka neke ki te taumata pūngao iti, ka tuku i te photon me te auau rite ki te photon taunga mai.
Ko te āhuatanga matua o te tukunga whakaohooho ko te ōrite o te photon i hangaia ki te mea taketake: he auau ōrite, he ahunga ōrite, ā, kāore e taea te wehewehe. Mā tēnei, ka huri te photon kotahi hei photon e rua rite tonu mā te tukanga tukunga whakaohooho kotahi. Ko te tikanga ka whakakahangia, ka whakanuia rānei te mārama - te kaupapa matua o te whakaputanga laser.
Tukunga Tūpono
Ka puta te tukunga ohorere ina heke ngā irahiko i te taumata pūngao teitei ki tētahi taumata iti iho, me te kore he awe o waho, ka tukuna te māramatanga (irahiko aukume) i te wā whakawhiti. Ko te pūngao photon ko E=E2−E1, te rerekētanga pūngao i waenga i ngā taumata e rua.
Ngā Tikanga mō te Whakaputa Taiaho
Waenga Whiwhinga Taiaho
Me whai reo whakanui e tika ana te whakaputanga taiaho, arā, he hau, he wai, he totoka, he haurua-ira rānei. Ko te mea nui ko te whakatutuki i te hurihanga taupori i roto i te reo, he āhuatanga e tika ana mō te putanga taiaho. He tino whai hua ngā taumata pūngao pumau mō te hurihanga taupori.
Pūtake Papu
Hei whakatutuki i te hurihanga taupori, me whakaoho te pūnaha ngota ki te whakanui ake i te maha o ngā matūriki i te taumata pūngao o runga.
Ko ngā tikanga noa ko:
- Te papu hiko: te tukunga hau mā te whakamahi i ngā irahiko kaha-nekehanga teitei
- Te papu whatu: te whakamāramatanga e ngā pūtake mārama kua pāoroorohia
- Te papu wera, te papu matū, me ētahi atu.
Ka kiia ēnei tikanga he papu. Me papu tonu kia mau tonu ai te nui o ngā matūriki i te taumata o runga i te taumata o raro, kia pumau ai te putanga taiaho.
Kaiwhakaoho
Mā te whakamahi i tētahi reo whakanui me te pūtake papu e tika ana, ka taea te whakatutuki i te hurihanga taupori, engari he ngoikore rawa te kaha o te tukunga whakaohooho mō te whakamahinga tūturu. Me whakanui ake i te kaha, e whakaratohia ana e tētahi resonator whatu.
Ko te resonator whatu he mea hanga mai i ngā whakaata whakaata e rua e whakanohoia ana ki ngā pito e rua o te taiaho kia whakarara:
- Kotahi te whakaata whakaata katoa
- Kotahi te whakaata whakaata wāhanga me te whakaata tuku wāhanga
Ka whakaatahia e te whakaata whakaata katoa te mārama katoa e tau mai ana i tōna ara taketake. Ka whakaatahia e te whakaata whakaata wāhanga ngā irahiko i raro i tētahi paepae pūngao ki roto i te reo, ko ngā irahiko i runga ake i te paepae ka tukuna atu hei mārama taiaho kua whakanuia.
Ka piupiu te mārama ki mua, ki muri i roto i te resonator, ka tīmata he tauhohenga mekameka o te tukunga whakaohooho, ka whakanuia pērā i te horonga hukarere hei whakaputa i te putanga taiaho kaha-tiketike.
He aha te Rama Papu?
He rama tuku hau kore mahi te rama xenon, he āhua ngongo tika te nuinga. Ko te tikanga he irahiko, he ngongo kuata, me te hau xenon (Xe) kua whakakīia.
He mea hanga ngā irahiko ki te konganuku he teitei te ira rewa, he teitei te pai o te tukunga irahiko, ā, he iti te pupuhi. He mea hanga te ngongo rama ki te karāhe kuata kaha, ātete pāmahana teitei, he nui te tuku, kua whakakiia ki te hau xenon.
He aha te tokotoko taiaho Nd:YAG?
Ko te Nd:YAG (Neodymium-doped Yttrium Aluminum Garnet) te rauemi taiaho totoka e whakamahia whānuitia ana.
He tioata pūtoru te YAG, he pakeke rawa, he kounga whatu pai rawa atu, ā, he kawe wera teitei. Ka whakakapia ētahi o ngā katote yttrium pūtoru i roto i te whatanga tioata e ngā katote neodymium trivalent, nō reira te ingoa ko te karāneti konumohe yttrium kua tāpirihia ki te neodymium.
Ngā Āhuatanga o te Reera
Te Hononga Pai
He pōrearea te ahunga, te āhua, me te wā o te mārama mai i ngā pūtake noa, ā, kāore e taea te arotahi ki tētahi pūwāhi kotahi ahakoa he karu arotahi.
He tino mārama te mārama taiaho: he auau parakore tōna, ka horapa i te ahunga kotahi i te āhua tino tika, ā, ka taea te arotahi ki tētahi wāhi iti he tino kukū te pūngao.
Te Aronga Tino Pai
He pai ake te ahunga o te hihi reihi i tētahi atu pūtake mārama, me te mea he rite tonu ki te hihi whakarara. Ahakoa ka anga atu ki te Marama (tata ki te 384,000 kiromita te tawhiti), he tata ki te 2 kiromita noa te whānui o te ira.
He pai te āhua kotahi
He tino whaiti te whānuitanga auau o te mārama taiaho mai i te tukunga whakaohooho. I roto i ngā kupu ngāwari, he tino pai te kotahi-tae o te taiaho — he tino parakore tōna "tae". He mea nui te kotahi-tae mō ngā tono tukatuka taiaho.
Teitei o te Kanapa
Ka whakamahia e te whakarewa reera te ahunga pai rawa atu me te kaha teitei o ngā hihi reera. Ka arotahihia te reera ki tētahi wāhi iti mā roto i tētahi pūnaha whatu, ka hangaia he pūtake wera tino kukū i roto i te wā poto rawa, ka whakarewahia te rauemi, ka hangaia he ira whakarewa me ngā hononga pumau.
Ngā Painga o te Whakarewa Taiaho
Ki te whakatauritea ki ētahi atu tikanga whakarewa, ko ngā mea e tukuna ana e te whakarewa laser:
- He nui te kukū pūngao, he nui te pai o te whakarewa, he tino tika, ā, he nui te ōwehenga hohonu-ki-te-whānui o ngā whakarewa.
- He iti te wera e tomo mai ana, he iti te rohe e pāngia ana e te wera, he iti te ahotea toenga me te whakarerekētanga.

- Whakarāhuitia kia rawaka te wāhi whakarewa me te matotoru o te rauemi mahi kia kaha ai, kia ātaahua ai hoki.
- Me whakarite kia ma te rauemi mahi, kia maroke hoki te taiao i te wā e whakarewaina ana.
Ngā Koranu Konumohe
- Ko te kaha whakaata teitei e hiahia ana ki te kaha tihi laser teitei.
- Ka pāngia e te ngatata i te wā e whakamahia ana te whakapiripiri ira, ka whakaiti i te kaha.
- Tērā pea ka tauhiuhi te hanganga o ngā rauemi; whakamahia ngā rauemi mata kounga teitei.
- He pai ake ngā hua me te rahi o ngā ira me te whānui o te pāorooro roa.
Parahi me ngā Koranu Parahi
- He teitei ake te whakaata i te konumohe; me nui ake anō te mana o te tihi taiaho.
- Me whakatītaha te pane o te taiaho ki tētahi koki.
- He uaua ake te whakarewa i ngā koranu parahi (parahi, kapuronikera, me ētahi atu) nā te mea he huānga koranu; me āta whiriwhiri i ngā tawhā.
Ngā hapa noa i roto i te whakarewa me ngā otinga o te taiaho
Ko ngā tawhā hē, ko te mahi hē rānei ka puta ai ngā hapa whakarewa, tae atu ki:
- Te tauhiuhi o te mata
- Te pūngao o roto o te whakarewa
- Ngā pakaru whakarewa
- Te whakarerekētanga o te whakarewa
Pāpaka Whakarewa
Ko te nuinga o te wā ka puta te tauhiuhi mai i te kaha nui rawa o te taiaho: he nui rawa te kaha e mimitihia ana e te mea mahi i roto i te wā poto, ka hua ake te mimiti nui o ngā rauemi me te tauhohenga kaha o te puna rewa.
Ka kino te āhua, te tika o te huihuinga, me te kaha o te whakarewanga i te piupiu.
Ngā Take
- Te mana tihi taiaho tino tiketike rawa.
- Te āhua ngaru whakarewa kāore i te tika, inā koa mō ngā rauemi whakaata-tiketike.
- Te wehewehenga rauemi e hua ake ai te mimiti pūngao nui ā-rohe.
- Te poke, ngā poke rānei ehara i te mea whakarewa i runga i te mata o te mea mahi.
- He matū iti te ira rewa i waenganui, i raro rānei i ngā wāhanga mahi, e whakaputa ana i te hau i te wā e whakarewaina ana.
- Ngā hanganga tuwhera kua kati e hua ai te whānui me te tauhiuhi o te hau.
Ngā otinga
- Arotauhia ngā tawhā: whakaitihia te mana tihi, whakamahia rānei ngā ngaru tihi.
- Whakamahia ngā rauemi mata e tika ana, e kounga teitei ana hoki.
- Whakakahangia te horoinga i mua i te whakarewa hei tango i te hinu me ngā poke.
- Whakapai ake i te hoahoa hanganga whakarewa.
Te Pūngao ā-Roto
Ko te pūngao te hapa tino kitea i roto i te whakarewanga taiaho. Nā te huringa wera tere me te poto o te ora o te puna rewa ka ārai i te hau kia puta, kia puta ai he pūngao.
Ngā momo noa: ngā pūwero hauwai, ngā pūwero haukini waro, me ngā pūwero hinga kōhao kī.
Ngā Kapiti Whakarewa
Ka tino whakaitihia te kaha me te roa o te mahi e ngā pakaru. Ka nui ake te mōrearea o te pakaru i te tere o te whakamahana me te whakamatao o te whakarewa taiaho.
Ko te nuinga o ngā kapiti whakarewa taiaho he kapiti wera, he mea noa i roto i ngā koranu konumohe me ngā maitai waro-tiketike/koranu-tiketike.
