Ko ngā huarahi hangarau matua o te whakarerekētangangā taiaho whānui-rārangime ngā kōhao o waho o te haurua-haurua
Ko ngā taiaho whānui-rārangi ka taea te whakarerekē te pūtake mō ngā tono whānui i roto i ngā mara pēnei i te ahupūngao ngota, te tirotiro ira, te mōhiohio matū, te whakawhitiwhiti kōrero ōrite, te rongo mamao, me te ine tika. I roto i ēnei mara, ka haere tonu ngā taiaho whānui-rārangi māmā ake, iti ake te utu, whaiti ake, me te whānuitanga whakarerekē whānui ki te akiaki i ngā tono hou o tēnei hangarau.
I roto i ngā tau 50 kua pahure ake nei, ko te hītori opūtake mārama ka taea te whakarerekēKo te nuinga o te wā, kua whakaatahia e te TLS Laser te whanaketanga o te hangarau laser. Kua whakakapia ngā laser tae tuatahi e ngā laser diode kōhao o waho (ECDL), ko ngā pūnaha mana-teitei ia e whakahaerehia ana e ngā laser totoka-āhua ka taea te whakarerekē (pēnei i ngā laser titanium-sapphire) me ngā laser Nd:YAG kua hurihia-auautia e whakamahi ana i ngā oscillator whatu (OPO). Kua whakakīia e ngā laser diode kāore he kōhao o waho pumau te pito mākete iti te utu me te mahi-iti ki ngā diode DFB arumoni me ngā diode DBR, me te whānui raina he whaiti ki te 500kHz. Nō nā tata nei, kua tīmata ngā laser muka me ngā laser muka auau-rerekē ki te whakakapi i te maha o ngā pūnaha totoka-āhua ki ngā hoahoa rerekē, e tuku ana i te mana teitei ake me te whakarerekētanga nui ake, te whānui raina whaiti rānei. I ēnei rā, ko te putanga mai o ngā heru auau ka taea te whakatutuki i ngā laser kua whakaū-auautia i tetahi roangaru me te pupuri tonu i te pumau me te tika. Heoi, ahakoa tēnei, ko te kōhao o wahorēhia haurua-irakei te mau tonu tōna mana hei pūtake mārama e whakamahia whānuitia ana i roto i te maha o ngā taiwhanga nā te mea he māmā noa iho, he maha ngā mahi, he pai te mahi, ā, he iti hoki te utu.
I tēnei wā, kua whānuitia te whakamahinga o ngā taiaho whānui-whāiti ka taea te whakarerekē me ngā haurua-ā-waho i roto i:
Te whakamatao me te hopu i te laser
Te whakapūpūtanga o Bose-Einstein
Ngā Whatu Kuantum: Te māramatanga kōpeke
Te māramatanga hikohiko me te māramatanga puhoi
Ngā paerewa wā me te auau
Te tirotiro taiaho
Ko ngā taiaho whānui-whāiti ka taea te whakarerekē he mea tito mai i tētahi kaiwhakahaere, he taiaho taiaho me tētahi kōwae whiriwhiri auau. Hei tauira, ko ngā whatanga e whakamahia ana mō te whiriwhiri me te whakahāngai i te auau taiaho, ngā tātari rānei i runga i te hanganga kanohi ngeru, me ētahi atu. Ko ngā āhuatanga nui o ngā taiaho whānui-whāiti ka taea te whakarerekē me ngā haurua-ā-waho ko te whānui-whāiti taiaho, te nekehanga auau iti, me te whānuitanga whakahāngai whānui, me ētahi atu. Ā, ko ēnei āhuatanga tino pai e whakawhirinaki ana ki tētahi ara iahiko taraiwa taiaho tino pai, te pumau ā-pūkaha whānui o te taiaho, me te kaupapa o te whiriwhiri auau. Hei whakatutuki i te pumau auau teitei ake o te taiaho, ka taea te tāpiri i ngā momo kōwae raka-auau taiaho rerekē. Hei tauira, mā te whakamahi i te hangarau whakapūmau auau PDH hei raka i te roangaru taiaho i runga i te kōwae tino pumau, ka taea te whakawhāiti i te whānui-whāiti o te taiaho ki te taumata o te 1 Hz, ā, ka taea e te pumau auau te eke ki te < 3× 10-15 @ 1 s.
