He tirohanga whānui mō te mana teiteirēhia haurua-irate wāhanga tuatahi o te whanaketanga
I te mea kei te whakapai tonu te pai me te mana, ka whakamahia ngā taiaho taiaho (taraiwa taiaho taiaho) ka whakakapi tonu i ngā hangarau tuku iho, ā, ka huri i te āhua o te hanga o ngā mea, ka taea ai te whakawhanake i ngā mea hou. He iti hoki te mārama ki ngā whakapainga nui o ngā reera haurua-rahi. I whakaaturia tuatahitia te hurihanga o ngā irahiko ki ngā reera mā roto i ngā haurua-rahi i te tau 1962, ā, he maha ngā whanaketanga tautoko kua whai ake nei kua akiaki i ngā whanaketanga nui i roto i te hurihanga o ngā irahiko ki ngā reera hua-teitei. Kua tautokohia e ēnei whanaketanga ngā tono nui mai i te rokiroki whatu ki te whatunga whatu ki te whānuitanga o ngā mara ahumahi.
Mā te arotake i ēnei ahunga whakamua me tō rātou ahunga whakamua katoa e whakaatu te kaha o te pānga nui ake, whānui ake hoki ki ngā wāhanga maha o te ōhanga. Inaa, mā te whakapai tonu i ngā taiaho haurua-rahi-kaha, ka tere ake te whānui o tōna mara tono, ā, ka nui te pānga ki te tipu ōhanga.
Pikitia 1: Te whakataurite i te kanapa me te ture a Moore mō ngā taiaho haurua-rahi
Ngā taiaho totoka e papuhia ana e te diode mengā taiaho muka
Nā ngā whanaketanga o ngā taiaho haurua-rahi te mana nui i ārahi ki te whanaketanga o te hangarau taiaho o muri mai, e whakamahia ai ngā taiaho haurua-rahi hei whakaoho (pamu) i ngā tioata kua tāpirihia (ngā taiaho totoka kua tāpirihia ki te diode) i ngā muka kua tāpirihia rānei (ngā taiaho muka).
Ahakoa he iti, he iti hoki te utu o ngā pūngao pūngao haurua-ira, e rua ngā herenga matua: kāore e rongoa te pūngao, ā, he iti noa iho te kanapa. Ko te tikanga, e rua ngā pūngao e hiahiatia ana mō ngā tono maha; ka whakamahia tētahi hei huri i te hiko hei tukunga pūngao pūngao, ā, ka whakamahia tētahi hei whakarei ake i te kanapa o taua tukunga.
Ngā taiaho āhua-totoka e papuhia ana e te diode.
I te mutunga o te tekau tau atu i 1980, ka tīmata te whakamahi i ngā taiaho haurua-ira hei pupuhi i ngā taiaho totoka-āhua ki te piki haere te aro nui ki ngā mahi arumoni. Ka whakaitihia e ngā taiaho totoka-āhua papu-diode (DPSSL) te rahi me te uaua o ngā pūnaha whakahaere wera (ko ngā whakamatao huringa te nuinga) me ngā kōwae whakanui, e whakamahi ana i ngā rama arc hei pupuhi i ngā tioata taiaho totoka-āhua.
Ka tīpakohia te roangaru o te taiaho haurua-ira i runga i te taupatupatu o ngā āhuatanga mimiti hihi me te reo whakanui o te taiaho totoka, ka taea te whakaiti i te kawenga wera ki te whakataurite ki te whānuitanga tuku whānui o te rama pewa. I runga i te rongonui o ngā taiaho neodymium-whakakīia e tuku ana i te roangaru 1064nm, kua noho te taiaho haurua-ira 808nm hei hua tino hua i roto i te hanga taiaho haurua-ira mō ngā tau neke atu i te 20.
Nā te kanapa ake o ngā taiaho haurua-aratau maha me te kaha ki te whakaū i ngā whānui raina tukunga whaiti mā te whakamahi i ngā kurupae Bragg papatipu (VBGS) i waenganui o te tekau tau atu i 2000, i taea ai te whakapai ake i te pai o te papu diode. Nā ngā āhuatanga mimiti whāiti me te whaiti o te 880nm kua nui ake te hiahia ki ngā taiaho papu kanapa teitei pumau. Mā ēnei taiaho mahi teitei ake ka taea te papu tika i te neodymium i te taumata taiaho o runga o te 4F3/2, ka whakaiti i ngā hapa irahiko, ā, ka whakapai ake i te tango aratau taketake i te mana toharite teitei ake, e kore nei e whakawhāitihia e ngā karāhe wera.
I te tīmatanga o te tekau tau tuarua o tēnei rautau, kua kite tātou i te pikinga nui o te mana o ngā taiaho aratau whakawhiti-kotahi 1064nm, tae atu ki ā rātou taiaho tahuritanga auau e mahi ana i ngā roangaru e kitea ana me ngā roangaru ultraviolet. I te mea he roa te ora o te kaha o runga o te Nd: YAG me te Nd: YVO4, ka whakaratohia e ēnei mahi DPSSL Q-switched te kaha pāoro teitei me te mana tihi, e pai ai mō te tukatuka rauemi ablative me ngā tono micromachining tino tika.
