He aha tetaiaho haurua-whakapā whānui
E whakamahia ana ngā taiaho i roto i te nuinga o ngā pūnaha pūoko muka whatu tohatoha (DOFS) nā te mea ka taea e rātou te werohanga whai huangā taiaho mana-teiteiki roto i ngā muka. Heoi, he maha ngā momo taiaho, ā, i konei ka whakaurua ngā momo matua i runga i te raupapa o te roa o te hononga, arā, te whakaiti i te whānui o te hihi. I te nuinga o te wā, he mea tito te taiaho i tētahi reo whakanui e whakanui ana i te mārama e horapa ana i roto, ā, e whakarato ana i te urupare hei tuku i te mārama kua whakanuia ki roto i te reo whakanui mō te huringa hihi. Nō reira, mai i te tukunga ohorere i roto i te reo whakanui, ka puta he ngaru mārama kaha ake, he hononga ake, ā, ko ōna āhuatanga e whakawhirinaki ana ki te reo whakanui me ngā āhuatanga urupare. I te nuinga o te wā, ka whakaratohia e te urupare he hanganga oro e hanga ana i tētahi, neke atu rānei ngā aratau, e tukuna ana ia aratau i roto i tētahi whānuitanga hihi whaiti.
Te whakapā whānuirēhia haurua-ira, te rēseri haurua-ira māmā rawa atu, me te tuatahi, he rohe whakanui rēseri haurua-ira i hangaia e te hononga pn o te rauemi āputa tika (pērā i te GaAs), me te urupare e whakaratohia ana e te whakaata mai i ngā taha kua horoia o te maramara rēseri; Ko te roa o ngā maramara rēseri he maha rau maikiromita te roa. Kua hangaia tēnei hanganga hononga hei aukati i ngā kaikawe utu me te horapa mārama i roto i te rohe whakanui. Hei diode, he hononga hiko kei ēnei taputapu i ngā taha e rua. I roto i tētahi taputapu whakapā whānui, ko te whānui o te irahiko o runga he maha tekau maikiromita (tata ki te 75 μm); Nō reira, ka hangaia e te tukunga mārama he rārangi i tēnei whānui, he aratau kotahi i roto i te papa e poutū ana ki te hononga, ā, ka whakaatu i tētahi tohatoha mara mārama maha-aratau matatini i roto i te papa e whakarara ana ki te hononga. Nā tēnei aratau tukunga, ka taea anake te hono pai i ngā rēseri whakapā whānui ki roto i ngā muka maha-aratau. Heoi, he tino teitei te mana o te rēseri whakapā whānui, ā, i raro i ngā tikanga whakahaere pulsed, ka taea e te taputapu irahiko 75 μm te whakaputa i te mana tihi neke atu i te 10 W.
Taiaho whakapā whānuiHe pai ngā diode mō ētahi momo pūnaha pūoko pāmahana tohatoha Raman maha-aratau, nā te mea kāore ēnei pūnaha e hiahia ana ki te parakore o te hihi. Ka taea hoki te whakamahi mō ngā pūoko e hangai ana ki te ngaronga, pērā i ngā pūnaha e whakamahi ana i te piko moroiti whakahaeretia hei tikanga pūoko.
