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 taiaho semiconductor mata-emitting te tito o te mata dissociation taiao o te karaihe semiconductor, a ka tukuna te kurupae putanga i te pito o mua o te laser.Ka taea e te taiaho momo wetewete taiaho te whakatutuki i te putanga mana tiketike, engari tona he porotiti te waahi whakaputa, he kino te kounga o te kurupae, me whakarereke te ahua o te kurupae ki te punaha hanga 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 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. Ma te whakanui ake i te waahi arataki ngaru ki te whakaiti i te kohinga wera ururua i roto i te rohe kaha ki te whakapai ake i te whakamaaramatanga o te wera, te whakanui ake i te waahi 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 taea kia tutuki i roto i te hanganga aratau ngaru kotahi.
Mo te arataki ngaru 100mm, ka taea e te taiaho te whakaputa i te mata kotahi tekau nga 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 hoki te ahua o te kurupae putanga ki te 100:1, e hiahia ana ki tetahi 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, a kare te mana whakaputa e piki kia rite ki te whanui o te whiu, na te kaha whakaputa o he iti rawa 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 tïpako kotahi, kia whakararangihia ia waeine tuku rama hei huinga ahua kotahi i roto i te ahunga o te tuaka puhoi, i te mea ka whakamahia te hangarau wehewehe whatu hei wehe i ia waeine whakaputa rama i roto i te raupapa. , kia kore ai e pokanoa tetahi ki tetahi, ka hanga i te lasing maha-aperture, ka taea e koe te whakanui ake i te mana whakaputa o te maramara katoa ma te whakanui ake i te maha o nga waeine whakauru marama. Ko tenei maramara laser semiconductor he maramara laser semiconductor (LDA), e mohiotia ana ano he pae laser semiconductor.
