Te whakamahinga hangarau okaiwhakarerekē hiko-whatu
He whakarerekētanga hiko-whatu（Kaiwhakatikatika EOM） he huānga whakahaere tohu e whakamahi ana i te pānga hiko-whatu hei whakarerekē i te hihi mārama. Ko tōna mātāpono mahi ka tutukihia mā te pānga Pockels (te pānga Pockels, arā, te pānga Pockels), e whakamahi ana i te āhuatanga e huri ana te taupū whakaata o ngā rauemi whatu kore-raina i raro i te mahi a ngā mara hiko.
Ko te hanganga taketake o te kaiwhakatikatika hiko-whatu he tioata (Pockels crystal) me te pānga hiko-whatu, ā, ko te rauemi noa ko te lithium niobate (LiNbO₃). Ko te ngaohiko e hiahiatia ana hei whakaoho i te huringa āhua ka kiia ko te ngaohiko haurua-ngaru. Mō ngā tioata Pockels, e hiahiatia ana he rau, he mano rānei ngā volts, nō reira te hiahia mō ngā whakakaha ngaohiko teitei. Ka taea e te ara iahiko hiko tika te whakawhiti i tētahi ngaohiko teitei i roto i ētahi nanohekona, ka taea ai te whakamahi i te EOM hei pana whatu tere; Nā te āhua kaha o ngā tioata Pockels, me whakarato e ēnei taraiwa he nui te iahiko (mō te whakawhiti tere, te whakarerekētanga rānei, me whakaiti te kaha hei whakaiti i te ngaronga pūngao). I ētahi atu wā, pērā i te wā e hiahiatia ana he iti noa te kaha, he iti noa te ngaohiko e hiahiatia ana mō te whakarerekētanga. Ko ētahi atu rauemi tioata kore-raina e whakamahia ana i roto i ngā kaiwhakatikatika hiko-whatu (Kaiwhakatikatika EOM) kei roto ko te pāhare pākawa titanate (KTP), te beta-barium borate (BBO, e tika ana mō te mana toharite teitei ake me/ranei ngā auau whakawhiti teitei ake), te lithium tantalate (LiTaO3), me te ammonium phosphate (NH4H2PO4, ADP, me ngā āhuatanga hiko-whatu motuhake).
Ngā whakarerekētanga hiko-whatu（Kaiwhakarerekē EO） e whakaatu ana i te pūmanawa tono nui i roto i te maha o ngā mara hangarau teitei:
1. Whakawhitiwhiti kōrero muka whatu: I roto i ngā whatunga whakawhitiwhiti kōrero hou, ko ngā whakarerekētanga hiko-whatu（Kaiwhakarerekē EO） e whakamahia ana hei whakarerekē i ngā tohu whatu, kia pai ai te tuku raraunga i ngā tawhiti roa. Mā te whakahaere tika i te āhua, i te kaha rānei o te mārama, ka taea te whakatutuki i te tuku mōhiohio tere-tiketike me te kaha-nui.
2. Te tirotiro ā-whatu tika: Ka whakarerekē te pūwhakatikatika hiko-whatu i te pūtake mārama i roto i te ine ā-whatu hei whakapai ake i te tika o te ine. Mā te whakarerekē tere i te auau, i te āhua rānei o te tohu whatu, ka taea te tautoko i te tātari me te tautuhi i ngā wāhanga matū matatini, ā, ka taea hoki te whakapai ake i te taumira me te aro o te ine ā-whatu.
3. Te tukatuka raraunga whatu mahi-teitei: te whakarerekētanga hiko-whatu i roto i te pūnaha rorohiko whatu me te tukatuka raraunga, mā te whakarerekētanga wā-tūturu o ngā tohu whatu hei whakapai ake i te tere me te ngāwari o te tukatuka raraunga. Mā te āhuatanga urupare tere o te EOM, ka taea te whakatutuki i te tukatuka me te tuku raraunga whatu tere-teitei me te iti-roa.
4. Hangarau taiaho: Ka taea e te pūwhakatikatika hiko-whatu te whakahaere i te āhua me te kaha o te hihi taiaho, e tautoko ana i te whakaahua tika, te tukatuka taiaho me ētahi atu whakamahinga. Mā te whakarerekē tika i ngā tawhā o te hihi taiaho, ka taea te whakatutuki i te tukatuka taiaho kounga teitei.
