Nā ngā tau maha o te rangahau me te whanaketanga, i angitu te whakawhanake a Lumispot Technology Co., Ltd. i tētahi taiaho pāorooro iti, māmā hoki, he kaha 80mJ, he auau tāruarua 20 Hz, ā, he roangaru haumaru mō te kanohi tangata 1.57μm. I tutuki tēnei hua rangahau mā te whakanui ake i te whai huatanga o te kōrero a KTP-OPO me te arotau i te putanga o te wae taiaho pūtake papu diode. E ai ki ngā hua whakamātautau, ka tutuki i tēnei taiaho te whakaritenga pāmahana mahi whānui mai i te -45 ℃ ki te 65 ℃ me te mahi tino pai, ā, ka eke ki te taumata matatau i Haina.
He taputapu ine tawhiti te Pūwero Reitihiko Pāhekoheko nā te mea he pūwero reitihiko e anga ana ki te ūnga, me ngā painga o te kaha ki te kimi tawhiti tino tika, te kaha ki te ārai i te pokanoa, me te hanganga kiato. He whānuitia te whakamahinga o tēnei hua i roto i te ine hangarau me ētahi atu mara. Ko tēnei tikanga kimi tawhiti reitihiko pāhekoheko te mea tino whānuitia te whakamahinga i roto i te tono ine tawhiti roa. I roto i tēnei pūwero tawhiti roa, he pai ake te whiriwhiri i te reitihiko totoka me te kaha teitei me te koki marara hihi iti, mā te whakamahi i te hangarau whakawhiti-Q hei whakaputa i ngā pūwero reitihiko nanohekona.
Ko ngā au e pā ana ki te ine tawhiti laser pulsed ko ēnei e whai ake nei:
(1) Te Awhe Ine Reiti Haumaru-kanohi Tangata: Kei te whakakapi haere te orooro whatu 1.57um i te tūranga o te awhe ine reiti roangaru 1.06um tuku iho i te nuinga o ngā mara ine awhe.
(2) Ine Awhe Reiti Mamao Iti, he iti te rahi, he māmā hoki.
I te whakapainga ake o te mahi a te pūnaha kimi me te whakaahua, e hiahiatia ana ngā taputapu kimi tawhiti mamao e taea ai te ine i ngā ūnga iti o te 0.1m² neke atu i te 20 km. Nō reira, he mea nui kia tere te ako i te taputapu kimi tawhiti teitei.
I ngā tau tata nei, i whakapau kaha a Lumispot Tech ki te rangahau, ki te hoahoa, ki te whakaputa me te hoko i te taiaho totoka haumaru-kanohi mō te roanga ngaru 1.57um me te koki marara hihi iti me te mahi whakahaere teitei.
Nō nā tata nei, i hangaia e Lumispot Tech tētahi taiaho hau whakamatao 1.57um haumaru-kanohi mō ngā roangaru me te kaha teitei me te hanganga kiato, i puta mai i te tono mahi i roto i te rangahau o te whakaiti i te ine tawhiti taiaho. Whai muri i te whakamātautau, e whakaatu ana tēnei taiaho i ngā tūmanako whānui mō te tono, he mahi tino pai, he kaha te urutau taiao i raro i te whānuitanga o te pāmahana mahi mai i - 40 ki te 65 nekehanga Celsius,
Mā te whārite e whai ake nei, me te rahinga pumau o ētahi atu tohutoro, mā te whakapai ake i te mana putanga tihi me te whakaiti i te koki marara hihi, ka taea te whakapai ake i te tawhiti ine o te ine tawhiti. Nō reira, ko ngā āhuatanga e rua: ko te uara o te mana putanga tihi me te koki marara hihi iti, te hanganga kiato o te taiaho me te mahi whakamatao-hau, koinei te wāhanga matua e whakatau ana i te kaha ine tawhiti o te ine tawhiti motuhake.
Ko te wāhanga matua hei whakatinana i te taiaho me te roangaru haumaru-kanohi tangata ko te tikanga o te oscillator whatu parametric (OPO), tae atu ki te kōwhiringa o te tioata kore-raina, te tikanga taurite ā-wāhanga me te hoahoa hanganga o roto OPO. Ko te kōwhiringa o te tioata kore-raina e whakawhirinaki ana ki te tauwehenga kore-raina nui, te paepae ātete kino teitei, ngā āhuatanga matū me te ā-tinana pumau me ngā tikanga tipu pakeke me ētahi atu, me whai mana te taurite ā-wāhanga. Kōwhiria he tikanga taurite ā-wāhanga kore-tino nui me te koki whakaae nui me te koki wehenga iti; Me whai whakaaro te hanganga kōhao OPO ki te whai huatanga me te kounga hihi i runga i te kaupapa o te whakarite i te pono. Ko te pihi huringa o te roangaru putanga KTP-OPO me te koki taurite ā-wāhanga, ina θ=90°, ka taea e te rama tohu te whakaputa tika i te taiaho haumaru-kanohi tangata. Nō reira, ka tapahia te tioata kua hangaia i te taha kotahi, ka whakamahia te taurite koki θ=90°，φ=0°, arā, te whakamahi i te tikanga taurite akomanga, ina ko te tauwehenga kore-raina whai hua o te tioata te mea nui rawa atu, ā, kāore he pānga marara.
I runga i te whakaaroaro whānui mō te take i runga ake nei, me te taumata whanaketanga o te tikanga me ngā taputapu taiaho ā-rohe o nāianei, ko te otinga hangarau arotau ko: Ka whakamahia e te OPO he hoahoa KTP-OPO ā-waho kore-tino e ōrite ana ki te wāhanga ā-rua o te akomanga II; ka honoa poutū ngā KTP-OPO e 2 ki roto i te hanganga takirua hei whakapai ake i te whai huatanga o te tahuritanga me te pono o te taiaho e whakaaturia ana i roto i tePikitia 1I runga ake.
Ko te pūtake papu he mea rangahau-ā-whaiaro, he mea whakawhanake hoki i te huinga taiaho haurua-whakamatao hiko, me te huringa mahi o te 2% te nuinga, te mana tihi 100W mō te pae kotahi, me te mana mahi katoa o te 12,000W. Ko te porowhita koki-matau, te whakaata whakaata-katoa me te pōrari e hanga ana i te kōhao whakaputanga pōrari kua pikohia, ā, ka hurihia te porowhita koki-matau me te pereti ngaru kia whiwhi ai i te putanga hononga taiaho 1064 nm e hiahiatia ana. Ko te tikanga whakarerekētanga Q he whakarerekētanga Q hiko-whatu kaha pēhanga i runga i te tioata KDP.
Pikitia 1E rua ngā tioata KTP e honoa ana i roto i te raupapa
I roto i tēnei whārite, ko Prec te mana mahi iti rawa ka kitea;
Ko te pout te uara putanga tihi o te mana mahi;
Ko D te kōhao pūnaha whatu whiwhi;
ko t te tukunga pūnaha whatu;
Ko θ te koki marara hihi tuku o te taiaho;
ko r te tere whakaata o te ūnga;
Ko A te horahanga whakawhiti-wāhanga ōrite e whaihia ana;
Ko R te whānuitanga ine nui rawa atu;
Ko σ te tauwehenga mimiti o te hau.
Pikitia 2: Te kōwae rarangi pae āhua-āwhata mā te whanaketanga-ā-koe ,
me te tokotoko karaihe YAG i waenganui.
TePikitia 2Ko ngā puranga pae āhua-pewa, e whakanoho ana i ngā tokotoko karaihe YAG hei reo taiaho i roto i te kōwae, me te kukū o te 1%. Hei whakatau i te taupatupatu i waenga i te nekehanga taiaho taha me te tohatoha ōrite o te putanga taiaho, i whakamahia he tohatoha ōrite o te rarangi LD i te koki o te 120 nekehanga. Ko te pūtake papu he roangaru 1064nm, e rua ngā kōwae pae rarangi piko 6000W i roto i te papu takirua haurua-haurua raupapa. Ko te kaha putanga he 0-250mJ me te whānui o te pāorooro o te 10ns me te auau taumaha o te 20Hz. Ka whakamahia he kōhao kua whakapikohia, ā, ka puta te taiaho roangaru 1.57μm i muri i te karaihe kore-raina KTP takirua.
Kauwhata 3Te tuhi ā-ahu o te taiaho pupuhi roangaru 1.57um
Kauwhata 4: Taputapu tauira taiaho pao roangaru 1.57um
Kauwhata 5:Putanga 1.57μm
Kauwhata 6:Te whai huatanga o te hurihanga o te pūtake papu
Te whakarerekē i te inenga pūngao taiaho hei ine i te mana putanga o ngā momo roangaru e rua. E ai ki te kauwhata e whakaaturia ana i raro nei, ko te hua o te uara pūngao ko te uara toharite e mahi ana i raro i te 20Hz me te wā mahi 1 meneti. I roto i ēnei, ko te pūngao i hangaia e te taiaho roangaru 1.57um he rerekētanga rite tonu me te whanaungatanga o te pūngao pūtake papu roangaru 1064nm. Ina rite te pūngao o te pūtake papu ki te 220mJ, ka taea e te pūngao putanga o te taiaho roangaru 1.57um te whakatutuki i te 80mJ, me te tere tahuritanga tae atu ki te 35%. Mai i te mea ka whakaputaina te rama tohu OPO i raro i te mahi a tetahi kiato mana o te rama auau taketake, ko tōna uara paepae he teitei ake i te uara paepae o te rama auau taketake 1064 nm, ā, ka tere te piki o tōna pūngao putanga i muri i te neke ake o te pūngao papu i te uara paepae OPO. Ko te whanaungatanga i waenga i te pūngao putanga OPO me te whai huatanga ki te pūngao putanga rama auau taketake e whakaaturia ana i roto i te pikitia, e kitea ai ka taea e te whai huatanga tahuritanga o te OPO te eke ki te 35%.
Hei whakamutunga, ka taea te whakatutuki i tētahi putanga pārō taiaho roangaru 1.57μm me te kaha neke atu i te 80mJ me te whānui pārō taiaho o te 8.5ns. Ko te koki wehewehenga o te hihi taiaho putanga mā te whakawhanui hihi taiaho he 0.3mrad. E whakaatu ana ngā whakatauira me ngā tātaritanga ka taea e te kaha ine whānuitanga o tētahi ine whānuitanga taiaho pārō e whakamahi ana i tēnei taiaho te neke atu i te 30km.
