He kupu whakataki ki te Edge Emitting Laser (EEL)
Kia whiwhi ai i te whakaputanga laser semiconductor teitei, ko te hangarau o naianei ko te whakamahi i te hanganga tukunga taha. Ko te resonator o te mata-emitting laser semiconductor he mea tito i te mata wehewehenga taiao o te karaihe semiconductor, a ka tukuna te kurupae putanga mai i te pito o mua o te laser.Ka taea e te taiaho momo whakakorikori mata te whakaputa mana teitei, engari ko tona waahi whakaputa he elliptical, he ngoikore te kounga o te kurupae me te ahua o te kurupae me whakarereke te ahua o te kurupae.
Ko te hoahoa e whai ake nei e whakaatu ana i te hanganga o te taiaho semiconductor mata-emitting. Ko te kohao whatu o EEL he whakarara ki te mata o te maramara semiconductor me te tuku i te taiaho ki te taha o te maramara semiconductor, ka taea te mohio ki te whakaputanga laser me te kaha teitei, te tere tere me te haruru iti. Heoi, ko te whakaputanga kurupae laser na te EEL i te nuinga o te waa he waahanga whakawhiti kurupae hangarite me te rereketanga koki nui, he iti te pai o te hono ki te muka me etahi atu waahanga whatu.
Ko te pikinga ake o te mana whakaputa EEL he iti na te kohi wera para i roto i te rohe hohe me te kino whatu i runga i te mata semiconductor. Na roto i te whakanui ake i te rohe o te kaiarahi ngaru ki te whakaiti i te whakaemi wera ururua i roto i te rohe kaha ki te whakapai ake i te tohanga wera, te whakanui ake i te rohe whakaputa marama ki te whakaiti i te kiato mana whatu o te kurupae ki te karo i te kino whatu, te mana whakaputa ki runga ki te maha rau milliwatts ka taea te whakatutuki i roto i te hanganga aratau ngaru kotahi.
Mo te arataki ngaru 100mm, ka taea e te taiaho kotahi te whakaputa i te tekau watts o te mana whakaputa, engari i tenei wa he tino maha-aratau te kaiarahi ngaru i runga i te rererangi o te maramara, a ka tae ano te ahua o te ahua o te kurupae whakaputa ki te 100: 1, me hiahia he punaha hanga kurupae uaua.
I runga i te whakaaro kaore he pakaruhanga hou i roto i te hangarau rauemi me te hangarau tipu epitaxial, ko te huarahi matua ki te whakapai ake i te mana whakaputa o te maramara laser semiconductor kotahi ko te whakanui ake i te whanui o te riipene o te rohe maramara o te maramara. Heoi, ko te whakanui ake i te whanui o te riipene he mea ngawari ki te whakaputa i te oscillation aratau teitei-whakawhiti me te oscillation rite kakawaea, ka tino whakaitihia te rite o te putanga marama, kaore hoki te mana whakaputa e piki kia rite ki te whanui o te riipene, na reira he iti rawa te mana whakaputa o te maramara kotahi. Hei whakapai ake i te mana whakaputa, ka puta mai te hangarau raupapa. Ko te hangarau e whakauru ana i nga waeine laser maha i runga i te taputapu kotahi, kia whakararangihia ia waeine maramara hei raupapa kotahi-ahu i roto i te ahunga tuaka puhoi, i te mea ka whakamahia te hangarau motuhake hei wehe i ia waeine marama i roto i te raupapa, kia kore ai e pokanoa tetahi ki tetahi, ka hanga i te waahi-maha, ka taea e koe te whakanui ake i te mana whakaputa o te maramara katoa ma te whakanui ake i te mana whakaputa o te maramara katoa. Ko tenei maramara laser semiconductor he maramara laser semiconductor (LDA), e mohiotia ana ano he pae laser semiconductor.
