He wafer tino tere te mahi teiteihangarau taiaho
Mana-teiteingā taiaho tino teree whakamahia whānuitia ana i roto i ngā mahi hanga matatau, ngā mōhiohio, ngā hikohiko iti, te rongoā koiora, te parepare ā-motu me ngā mara hōia, ā, he mea nui te rangahau pūtaiao e tika ana hei whakatairanga i te auahatanga pūtaiao me te hangarau ā-motu me te whanaketanga kounga teitei. He poro angiangipūnaha taiahoHe nui te hiahia mō tēnei hangarau i roto i ngā mara pūtaiao me ngā mara ahumahi, nā ōna painga o te kaha toharite teitei, te kaha pāoro nui me te kounga hihi pai rawa atu, ā, kua tino arohia e ngā whenua o te ao katoa.
Nō nā tata nei, kua whakamahia e tētahi rōpū rangahau i Haina te waeine wafer i whakawhanakehia e rātou anō me te hangarau whakanui whakaora hei whakatutuki i te wafer tino tere (pūmautanga teitei, mana teitei, kounga hihi teitei, tino whai huatanga).rēseriputanga. Mā te hoahoa o te kōhao whakakaha whakaora me te whakahaere i te pāmahana mata me te pumau ā-pūkaha o te karaihe kōpae i roto i te kōhao, ka tutuki te putanga taiaho o te kaha pāoro kotahi >300 μJ, te whānui pāoro <7 ps, te mana toharite >150 W, ā, ka taea e te pai o te tahuritanga mārama-ki-mārama te eke ki te 61%, koinei hoki te pai o te tahuritanga whatu teitei rawa atu kua pūrongohia tae noa ki tēnei wā. Ko te tauwehenga kounga hihi M2<1.06@150W, 8h pumau RMS<0.33%, he tohu tēnei whakatutukitanga i tētahi ahunga whakamua nui i roto i te taiaho wafer tere-teitei, ka whakarato i ngā huarahi maha atu mō ngā tono taiaho tere-teitei.
Te auau auau teitei, te pūnaha whakanui whakahou anga kaha teitei
Kei te Pikitia 1 te hanganga o te whakakaha irahiko wafer. Kei roto ko te pūtake purapura muka, he pane irahiko poro angiangi me te kōhao whakakaha whakaora. I whakamahia he oscillator muka kua tāpirihia ki te ytterbium me te mana toharite o te 15 mW, he roangaru pokapū o te 1030 nm, he whānui pāorooro o te 7.1 ps me te tere whakahoki o te 30 MHz hei pūtake purapura. Ka whakamahia e te pane irahiko wafer he karaihe Yb: YAG i hangaia i te kāinga me te diameter o te 8.8 mm me te matotoru o te 150 µm me te pūnaha papu 48-whiu. Ka whakamahia e te pūtake papu he LD raina kore-phonon me te roangaru maukati 969 nm, e whakaiti ana i te hapa kuantum ki te 5.8%. Ka taea e te hanganga whakamatao ahurei te whakamatao i te karaihe wafer me te whakarite i te pumau o te kōhao whakaora. Ko te kōhao whakakaha whakaora he pūtau Pockels (PC), he Polarizer Kiriata Angiangi (TFP), he Pereti Hauwhā-Ngaru (QWP) me te resonator pumau-teitei. Ka whakamahia ngā wehewehe hei ārai i te mārama kua whakanuia kia kore ai e pakaru te pūtake purapura. Ka whakamahia he hanganga wehewehe kei roto ko te TFP1, te Rotator me ngā Pereti Haurua-Ngaru (HWP) hei wehewehe i ngā purapura whakauru me ngā pāorooro kua whakanuia. Ka tomo te pāorooro purapura ki te rūma whakanui whakaora mā te TFP2. Ka honoa ngā tioata Barium metaborate (BBO), te PC, me te QWP hei hanga i tētahi pana whatu e whakamahi ana i te ngaohiko teitei i ia wā ki te PC hei hopu i te pāorooro purapura me te horapa ki mua, ki muri i roto i te kōhao. Ka wiri te pāorooro e hiahiatia ana i roto i te kōhao, ā, ka whakanuia pai i te wā horapa hoki mā te whakarerekē pai i te wā pēhi o te pouaka.
He pai te mahi whakaputa a te whakakaha whakaora wafer, ā, ka whai wāhi nui ia ki ngā mara hangahanga teitei pēnei i te whakaahua ultraviolet tino kaha, te pūtake papu attosecond, ngā hikohiko 3C, me ngā waka pūngao hou. I taua wā anō, e tūmanakohia ana ka whakamahia te hangarau taiaho wafer ki ngā waka nui tino kaha.ngā taputapu taiaho, e whakarato ana i tētahi tikanga whakamātautau hou mō te hanganga me te kimi matatau i ngā mea i runga i te tauine ātea nano me te tauine wā femtosecond. Me te whāinga ki te whakatutuki i ngā hiahia nui o te whenua, ka arotahi tonu te tīma kaupapa ki te auahatanga hangarau reera, ki te pakaru atu i te whakaritenga o ngā tioata reera kaha-teitei rautaki, me te whakapai ake i te kaha rangahau me te whanaketanga motuhake o ngā taputapu reera i roto i ngā mara o te mōhiohio, te pūngao, ngā taputapu teitei me ētahi atu.
