Hei whakatutuki i te hiahia o te tangata ki ngā mōhiohio e piki haere ana, kei te piki haere te tere tuku o ngā pūnaha whakawhitiwhiti muka whatu i ia rā, i ia rā. Ka whanake te whatunga whakawhitiwhiti muka whatu ā muri ake nei ki te whatunga whakawhitiwhiti muka whatu me te tere tino teitei, te kaha tino nui, te tawhiti tino roa, me te pai o te whānuitanga tino teitei. He mea nui te tuku. Ko te tuku tohu whatu tere-teitei he mea hanga i te nuinga o te wā mai i te laser e whakaputa ana i te kaikawe whatu, he taputapu whakaputa tohu hiko whakarerekē, me te whakarerekē hiko-whatu tere-teitei e whakarerekē ana i te kaikawe whatu. Ki te whakatauritea ki ētahi atu momo whakarerekē o waho, he pai ngā painga o ngā whakarerekē hiko-whatu lithium niobate o te auau mahi whānui, te pumau pai, te ōwehenga mate teitei, te mahi pumau, te tere whakarerekē teitei, te tangi iti, te hononga ngāwari, te hangarau whakaputa pakari, me ētahi atu. He whānui te whakamahinga i roto i ngā pūnaha tuku whatu tere-teitei, kaha-nui, me te tawhiti-roa.
He tawhā ā-tinana tino nui te ngaohiko haurua-ngaru o te kaiwhakarerekē hiko-whatu. E tohu ana i te huringa o te ngaohiko pīrori e rite ana ki te kaha o te mārama putanga o te kaiwhakarerekē hiko-whatu mai i te iti rawa ki te mōrahi. Ka whakatau nui i te kaiwhakarerekē hiko-whatu. He mea nui te ine tika me te tere i te ngaohiko haurua-ngaru o te kaiwhakarerekē hiko-whatu hei whakapai ake i te mahi a te taputapu me te whakapai ake i te whai huatanga o te taputapu. Kei roto i te ngaohiko haurua-ngaru o te kaiwhakarerekē hiko-whatu te DC (haurua-ngaru
(ngaohiko me te auau irirangi) ngaohiko haurua-ngaru. Ko te mahi whakawhiti o te whakarerekētanga hiko-whatu e whai ake nei:
Kei roto i ēnei ko te mana whatu putanga o te pūwhakarerekētanga hiko-whatu;
Ko te mana whatu tāuru o te modulator;
Ko te ngaronga whakaurunga o te modulator electro-whatu;
Ko ngā tikanga o nāianei mō te ine i te ngaohiko haurua-ngaru ko te whakaputa uara tino nui me te tikanga whakarea auau, e taea ai te ine i te ngaohiko haurua-ngaru o te au tika (DC) me te ngaohiko haurua-ngaru o te auau reo irirangi (RF) o te modulator.
Ripanga 1 Te Whakataurite i ngā Tikanga Whakamātautau Ngaohiko Haurua-ngaru e rua

| Ngā painga whakamātautau | ngāwari ki te whakatutuki | Whakamātautau tika Ka taea te whiwhi i te ngaohiko haurua-ngaru DC me te ngaohiko haurua-ngaru RF i te wa kotahi |
| Ngā ngoikoretanga o te whakamātautau | Kāore te whakamātautau i te tika mō te wā roa me ētahi atu āhuatanga Ngaohiko haurua-ngaru DC whakamātautau tika a te pāhihi | He roa te wā Kāore te whakamātautau i te tika mō ngā āhuatanga pēnei i te hapa whakatau nui o te whakapōturitanga o te ngaru. |
Ko tāna mahi penei:
(1) Tikanga uara tino nui
Ko te tikanga uara tino nui ka whakamahia hei ine i te ngaohiko haurua-ngaru DC o te kaiwhakarerekē hiko-whatu. Tuatahi, me te kore he tohu whakarerekē, ka whiwhihia te pihi mahi whakawhiti o te kaiwhakarerekē hiko-whatu mā te ine i te ngaohiko pīanga DC me te huringa kaha o te mārama putanga, ā, mai i te pihi mahi whakawhiti ka whakatauhia te pūwāhi uara mōrahi me te pūwāhi uara iti rawa, ka whiwhi i ngā uara ngaohiko DC e rite ana, Vmax me Vmin. Hei whakamutunga, ko te rerekētanga i waenga i ēnei uara ngaohiko e rua ko te ngaohiko haurua-ngaru Vπ=Vmax-Vmin o te kaiwhakarerekē hiko-whatu.
(2) Tikanga whakarea auau
I whakamahia te tikanga whakarea auau hei ine i te ngaohiko haurua-ngaru RF o te modulator hiko-whatu. Tāpirihia te rorohiko whakahāngai DC me te tohu whakarea AC ki te modulator hiko-whatu i te wā kotahi hei whakatika i te ngaohiko DC ina hurihia te kaha o te mārama putanga ki te uara mōrahi, mōrahi rānei. I taua wā anō, ka kitea i runga i te oscilloscope takirua ka puta te hapa whakarea auau o te tohu whakarea putanga. Ko te rerekētanga anake o te ngaohiko DC e rite ana ki ngā hapa whakarea auau e rua e tata ana ko te ngaohiko haurua-ngaru RF o te modulator hiko-whatu.
Whakarāpopototanga: Ka taea e te tikanga uara tino nui me te tikanga whakarea auau te ine i te ngaohiko haurua-ngaru o te pūwhakarerekē hiko-whatu, engari hei whakatairite, he roa ake te wā ine mō te tikanga uara kaha, ā, ko te roa ake o te wā ine ka hua mai i te mea ka rerekē te mana whatu putanga o te taiaho, ā, ka puta he hapa ine. Me matawai e te tikanga uara tino nui te rītaha DC me te uara takahanga iti, ā, me tuhi i te mana whatu putanga o te pūwhakarerekē i te wā kotahi kia whiwhi ai i te uara ngaohiko haurua-ngaru DC tika ake.
Ko te tikanga whakarea auau he tikanga mō te whakatau i te ngaohiko haurua-ngaru mā te tirotiro i te āhua o te ngaru whakarea auau. Ina tae te ngaohiko pīanga ki tētahi uara motuhake, ka puta te whakarea auau, ā, kāore e tino kitea te whakarea ngaru. Ehara i te mea ngāwari ki te tirotiro mā te kanohi tahanga. Mā tēnei, ka nui ake ngā hapa ka puta, ā, ko tāna e ine ko te ngaohiko haurua-ngaru RF o te whakarerekētanga hiko-whatu.
