He Kupu Whakataki ki te Taiaho Whakaputa Tapa (EEL)
Hei whiwhi i te putanga taiaho haurua-haurua mana-teitei, ko te hangarau o nāianei ko te whakamahi i te hanganga tuku taha. Ko te resonator o te taiaho haurua-haurua tuku taha he mea hanga mai i te mata wehewehe taiao o te karaihe haurua-haurua, ā, ka tukuna te hihi putanga mai i te pito o mua o te taiaho. Ka taea e te taiaho haurua-haurua momo tuku taha te whakatutuki i te putanga mana teitei, engari he porowhita tōna wāhi putanga, he ngoikore te kounga o te hihi, ā, me whakarerekē te āhua o te hihi mā te whakamahi i te pūnaha hanga hihi.
E whakaatu ana te hoahoa e whai ake nei i te hanganga o te rēseri haurua-whakaputa taha. Kei te whakarara te kōhao whatu o te EEL ki te mata o te maramara haurua-whakaputa, ā, ka tukuna te rēseri i te taha o te maramara haurua-whakaputa, ka taea te whakaputa i te putanga rēseri me te kaha teitei, te tere teitei me te haruru iti. Heoi, ko te putanga hihi rēseri e te EEL he whānui te wāhanga whakawhiti hihi kore-taurite me te rerekētanga koki nui, ā, he iti te pai o te hononga ki te muka, ki ētahi atu wāhanga whatu rānei.
Ka whakawhāitihia te pikinga o te mana whakaputa EEL e te kohikohinga wera para i roto i te rohe hohe me te kino whatu i runga i te mata semiconductor. Mā te whakanui ake i te horahanga arataki ngaru hei whakaiti i te kohikohinga wera para i roto i te rohe hohe hei whakapai ake i te tohatoha wera, te whakanui ake i te horahanga putanga mārama hei whakaiti i te kiato mana whatu o te hihi hei karo i te kino whatu, ka taea te whakatutuki i te mana whakaputa tae atu ki te rau milliwatts i roto i te hanganga arataki ngaru aratau whakawhiti kotahi.
Mō te arataki ngaru 100mm, ka taea e te taiaho tuku-taha kotahi te whakatutuki i ngā tekau watts o te mana putanga, engari i tēnei wā he maha-aratau te arataki ngaru i runga i te papa o te maramara, ā, ka eke hoki te ōwehenga āhua hihi putanga ki te 100:1, me whai pūnaha hanga hihi matatini.
I runga i te whakaaro kāore he whanaketanga hou i roto i te hangarau rauemi me te hangarau tipu epitaxial, ko te huarahi matua ki te whakapai ake i te mana putanga o te maramara reihi kotahi-haurua ko te whakanui ake i te whānui o te rohe kanapa o te maramara. Heoi, mā te whakanui rawa i te whānui o te rīpene ka ngāwari te whakaputa i te oscillation aratau-teitei whakawhiti me te oscillation rite-miraka, ka tino whakaiti i te ōritetanga o te putanga mārama, ā, kāore te mana putanga e piki rite ki te whānui o te rīpene, nō reira he tino iti te mana putanga o te maramara kotahi. Hei whakapai ake i te mana putanga, ka puta mai te hangarau rarangi. Ka whakauruhia e te hangarau ngā waeine reihi maha ki runga i te papa kotahi, kia rite ai ia waeine tuku mārama hei rarangi kotahi-ahu i te ahunga tuaka puhoi, mena ka whakamahia te hangarau wehewehe whatu hei wehe i ia waeine tuku mārama i roto i te rarangi, kia kore ai e pokanoa tetahi ki tetahi, ka hangaia he lasing maha-aperture, ka taea e koe te whakanui ake i te mana putanga o te maramara katoa mā te whakanui ake i te maha o ngā waeine tuku mārama kua whakauruhia. Ko tēnei maramara taiaho haurua-waenga he maramara huinga taiaho haurua-waenga (LDA), e mōhiotia ana hoki ko te pae taiaho haurua-waenga.
