Te Waenga Whakawhiwhi: He Hononga o te Hangarau Irahiko me te Hangarau Whatu
Ngā Ahumahi Kuantum i roto i te Waenga Whakanui
Ko te reo whakanui te wāhi e puta ai te tukanga matua o te whakanui mārama, he āhuatanga e tino pūtake ana ki te miihini irahiko. Ko te taunekeneke i waenga i ngā āhua pūngao me ngā matūriki i roto i te reo e whakahaerehia ana e ngā mātāpono o te tukunga whakaoho me te hurihanga taupori. Ko te whanaungatanga nui i waenga i te kaha o te mārama (I), te kaha tīmatanga (I0), te wāhanga whakawhiti (σ21), me ngā tau matūriki i ngā taumata pūngao e rua (N2 me N1) e whakaahuahia ana e te whārite I = I0e^(σ21(N2-N1)L). Ko te whakatutuki i te hurihanga taupori, ina neke atu a N2 i te N1, he mea nui mō te whakanui, ā, he tūāpapa o te ahupūngao taiaho [1].
Ngā Pūnaha Taumata-Toru me ngā Pūnaha Taumata-Whā
I roto i ngā hoahoa taiaho mahi, e whakamahia whānuitia ana ngā pūnaha taumata-toru me ngā taumata-whā. Ahakoa he māmā ake ngā pūnaha taumata-toru, me nui ake te pūngao hei whakatutuki i te hurihanga taupori nā te mea ko te taumata taiaho o raro te āhua whenua. I tētahi atu taha, ka tukuna e ngā pūnaha taumata-whā he huarahi whai hua ake ki te hurihanga taupori nā te tere o te pirau kore-ira mai i te taumata pūngao teitei ake, ka nui ake te horapa i roto i ngā tono taiaho hou.2].
Is Karāhe kua pania ki te erbiumhe reo whakanui?
Ae, ko te karāhe i tāpirihia ki te erbium he momo reo whakanui e whakamahia ana i roto i ngā pūnaha taiaho. I roto i tēnei horopaki, ko te "whakauru" e pā ana ki te tukanga tāpiri i tētahi nui o ngā iona erbium (Er³⁺) ki te karāhe. Ko te erbium he huānga whenua onge, ina whakauruhia ki roto i te karāhe, ka taea te whakanui ake i te mārama mā te tukunga whakaohooho, he tukanga taketake i roto i te mahi taiaho.
He mea tino rongonui te karāhe kua tāpirihia ki te erbium mō tōna whakamahinga i roto i ngā taiaho muka me ngā whakakaha muka, inā koa i roto i te umanga whakawhitiwhiti kōrero. He tino pai mō ēnei tono nā te mea ka whakakaha pai i te mārama i ngā roangaru tata ki te 1550 nm, he roangaru matua mō ngā whakawhitiwhitinga muka whatu nā te iti o tōna ngaronga i roto i ngā muka silica paerewa.
Teerbiumka mimitihia e ngā iona te mārama o te papu (he maha ngā wā mai i tetaiaho taiaho) ā, ka whakaohokia ki ngā āhua pūngao teitei ake. Ina hoki rātou ki te āhua pūngao iti iho, ka tukuna e rātou ngā photon i te roangaru hiko, ka whai wāhi ki te tukanga laser. Nā tēnei ka waiho te karāhe kua pania ki te erbium hei reo whakanui whai hua, ā, he whānuitia te whakamahinga i roto i ngā hoahoa laser me te whakakaha.

Ngā Tikanga Papu: Te Mana Whakahaere i Muri i ngā Taiaho
Ngā Huarahi Kanorau hei Whakatutuki i te Hurihanga Taupori
He mea nui te whiriwhiri i te tikanga papu i roto i te hoahoa taiaho, e awe ana i ngā mea katoa mai i te whai huatanga ki te roangaru putanga. He mea noa te papu whatu, mā te whakamahi i ngā puna mārama o waho pēnei i ngā rama rama, i ētahi atu taiaho rānei, i roto i ngā taiaho totoka me ngā taiaho tae. Ko ngā tikanga tuku hiko e whakamahia ana i roto i ngā taiaho hau, ko ngā taiaho haurua-ira ia e whakamahi ana i te werohanga irahiko. Ko te whai huatanga o ēnei tikanga papu, inā koa i roto i ngā taiaho totoka papu-diode, he arotahi nui tēnei o ngā rangahau hou, e tuku ana i te whai huatanga me te kiato teitei ake.3].
Ngā Whakaaro Hangarau mō te Whai Hua o te Papu
Ko te whai huatanga o te tukanga papu he wāhanga nui o te hoahoa taiaho, e pā ana ki te mahi whānui me te pai o te tono. I roto i ngā taiaho totoka, ko te kōwhiringa i waenga i ngā rama mura me ngā taiaho taiaho hei pūtake papu ka pā nui ki te whai huatanga o te pūnaha, te kawenga wera, me te kounga o te hihi. Ko te whanaketanga o ngā taiaho taiaho kaha-teitei, whai hua-teitei kua huri i ngā pūnaha taiaho DPSS, ka taea ai ngā hoahoa kiato me te whai hua ake.4].
Te Kōhao Whatu: Te Hanga i te Hiko Reera
Te Hoahoa Poka: He Mahi Taurite i waenganui i te Ahupūngao me te Hangarau
Ehara te kōhao whatu, te kaiwhakaoho rānei, i te mea he wāhanga kore mahi noa iho engari he wāhi kaha ki te hanga i te hihi laser. Ko te hoahoa o te kōhao, tae atu ki te piko me te whakaritenga o ngā whakaata, he mea nui ki te whakatau i te pumau, te hanganga aratau, me te putanga o te laser. Me hoahoa te kōhao kia whakarei ake i te whiwhinga whatu me te whakaiti i ngā ngaronga, he wero e whakakotahi ana i te hangarau whatu me ngā whatu ngaru.5.
Ngā Āhuatanga o te Oscillation me te Kōwhiringa Aratau
Kia puta ai te wiri o te taiaho, me nui ake te pikinga e whakaratohia ana e te reo i ngā ngaronga i roto i te kōhao. Ko tēnei āhuatanga, me te whakaritenga mō te taupatupatu ngaru honohono, e kī ana ko ētahi momo roa anake ka tautokona. Ko te roa ā-tinana o te kōhao me te taupū whakaata o te reo pikinga ka pāngia e te mokowā aratau me te hanganga aratau whānui.6].
Whakamutunga
Ko te hoahoa me te whakahaere o ngā pūnaha taiaho e kapi ana i te whānuitanga o ngā mātāpono ahupūngao me te hangarau. Mai i te miihini matū e whakahaere ana i te reo whiwhi ki te hangarau matatini o te kōhao whatu, he mahi nui tā ia wāhanga o te pūnaha taiaho i roto i tana mahi whānui. Kua whakaratohia e tēnei tuhinga he tirohanga ki te ao matatini o te hangarau taiaho, e tuku ana i ngā māramatanga e hono ana ki te māramatanga matatau o ngā ahorangi me ngā miihini whatu i roto i te mara.
