Ko te hanganga matua o tētahitaiaho muka aratau-kotahi
Te mahi tino pai o te aratau kotahimuka rēserii ahu mai i te hoahoa hanganga ā-roto tino tika. Ko te mahi tahi whai hua i waenga i ngā wāhanga katoa te tūāpapa mō te whakatutuki i te putanga taiaho pumau me te kounga teitei.
Hei tauira, ka whakamahia he taiaho 976nm me te pai o te hurihanga hiko-whatu hei utu i te muka kua tāpirihia, kātahi ka whakamahia he rama purapura 1064nm me te kounga hihi pai hei ārahi i te muka kua tāpirihia kia tukuna he taiaho 1064nm me te pūngao teitei ake. Ko te teitei ake o te pūngao taiaho 1064nm e hiahiatia ana, ko te nui ake o te mana me te nui o te pūtake papu e hiahiatia ana.
He whakamārama taipitopito mō ngā wāhanga matua
Ko te pūtake papu te pūtake pūngao o terēseri, he tikanga herēhia haurua-irahe taio, ko tōna roangaru tukunga e ōrite ana ki te tihi mimiti o te reo whakanui (hei tauira, ko te muka i tāpirihia ki te ytterbium e ōrite ana ki te roangaru o te 915nm, 976nm rānei). Me whai hononga ā-wāhi teitei hoki te pūtake mārama papu mō te taiaho aratau-kotahi. Nō reira, he maha ngā wā ka whakamahia ngā taiaho muka-honohono aratau-kotahi hei whakarite kia taea te werohanga pai o te mārama papu ki roto i te matua muka aratau-kotahi pai.
2. Ko ngā muka tāpiri te pūtake o te whakaputanga taiaho, ā, ko te nuinga he muka karāhe kuata kua tāpirihia ki ngā huānga whenua onge. Ko ngā katote tāpiri noa ko te ytterbium (Yb³⁺), te erbium (Er³⁺), te thulium (Tm³⁺), me ētahi atu, e rite ana ki ngā roopu roangaru putanga rerekē (pēnei i te 1064nm, 1550nm, 2μm, me ētahi atu). Me tino hangaia te roa o te muka tāpiri kia tino mimiti te mārama papu me te pupuri tonu i te huringa opto-whatu tino whai hua.
3. Ko te momo whakatinanatanga tino noa o te kōhao whakapūmau ko te takirua whatu muka Bragg. Ka hangaia he whatu mā te whakaatu i ngā muka whatu ki ngā taha whakararuraru laser ultraviolet, ka puta he huringa tuturu i roto i te taupū whakaata o ō rātou rohe matua. Mā te whakahaere i te wā me te roa o te whatu, ka taea te whakahaere tika i te roanga ngaru waenga me te whānui o tōna whakaata. Kāore e hiahiatia he wāhanga motuhake pēnei i ngā karāhe whatu mō tēnei hanganga kōhao whakapūmau muka-katoa, ka nui ake te whakapai ake i te pumau me te kaha ārai-whakararuraru o te pūnaha.
4. Kei muri i te whatanga pito putanga te pūnaha whakaputa hihi whakarara. Ko tana mahi he huri i te laser rerekē e tukuna ana mai i te muka whatu ki te mārama whakarara whakarara, ki te arotahi atu rānei ki te mata mahi. Kei roto i tēnei pūnaha ngā karāhe arotahi-whaiaro, ngā rōpū karāhe iti-iti rānei, ā, he hanganga miihini tika hei whakarite i te tika o te whakarārangi. Ka taea e te hoahoa whatu kounga teitei te whakaiti i ngā hapa me te whakarite kia mau tonu te tohatoha Gaussian pai o te hihi putanga.
