I konei, i tirotirohia te paheketanga o te mate me te whakarei ake i te mahi taiaho o Nd:YAG.Ma te whakamahi i te 0.6 at.% Nd:YAG rakau uku me te 3 mm te whanui me te 65 mm te roa, teKo te whakarea marara me te whakarea absorption i 1064 nm i inehia kia 0.0001 cm-1 me te 0.0017 cm-1.Mo te whakamatautau taiaho 808 nm taha-pupuhia, i tutuki te mana whakaputa toharite o 44.9 W me te pai o te huringa whatu-ki-optical o 26.4%, he rite tonu ki tera o te 1 at.% kotahi karaihe.Ma te whakamahi i te kaupapa 885 nm tika-whakamutunga, ko nga whakamatautau taiaho e whai ake nei i whakaatu i te kaha o te mata o te 62.5% me te mana whakaputa teitei o te 144.8 W i riro mai i te mana papu o te 231.5 W. Ko tenei tae noa ki tenei wa ko te tino pai o te hurihanga matakite kua riro. i roto i te Nd:YAG taiaho uku ki to tatou matauranga.E whakaatu ana ko te kaha teitei me te kaha teitei o te whakaputa laser ka taea te whakaputa e te kounga whatu teitei Nd:YAG ceramic rod me te 885 nm te hangarau pupuhi tika.
Ko tenei pepa e whakaatu ana i te kaha pupuhi nui, te whanui raina whaiti, te taiaho waenganui-infrared (MIR) ki te 6.45 µm, i runga i te BaGa4Se7 (BGSe) tioata whatu oscillator parametric (OPO) i maemaa e 1.064 µm laser.Ko te nui o te kaha o te hiko i te 6.45 µm kua eke ki te 1.23 mJ, he 24.3 ns te whanui o te putere me te reeti tukurua 10 Hz, e rite ana ki te kaha hurihanga whatu-whatu o 2.1%, mai i te rama papu 1.064 µm ki te marama mangere 6.45 µm.Ko te whanui raina marama mangere he 6.8 nm. I tenei wa, i tika ta matou tatau i te ahua o te wahanga OPO i te karaihe BGSe e maminga ana e te laser 1.064 µm, a ka mahia he punaha whaihanga nama hei tātari i nga ahuatanga whakauru-putanga i te 6.45 µm, me te pānga o te roa tioata i runga i te tōtika faafariuraa.He pai te whakaaetanga i waenga i te ine me te whaihanga.Ki runga i o maatau mohiotanga, koinei te puopu hiko teitei rawa atu i te 6.45 µm, me te whanui raina whaiti mo nga laser MIR ns-katoa i roto i te BGSe-OPO i maemaa e te oscillator 1.064 µm ngawari.Ko tenei punaha OPO 6.45 µm ngawari me te ngawari, he nui te kaha o te pupuhi me te whanui raina whaiti, ka taea te whakatutuki i nga whakaritenga mo te tapahi kiko me te whakapai ake i te tika o te whakakore i te kiko.
I roto i tenei pepa, ka whakaatu matou i te langasite (LGS) electro-optic Ho:YAG cavity-dumped laser e pehi ana i te ti'aturi o te roanga o te pupuhi i roto i nga laser whakahuri-Q.He 7.2 ns te roanga o te paheketanga i tutuki i te tere tukurua o te 100 kHz.Ko te painga mai i te karaihe LGS karekau he tino whakamuri whakamuri mowhiti piezoelectric me te whakamaaramatanga o te waiariki, i tutuki he tereina pupuhi pumau i te mana whakaputa o 43 W. Mo te wa tuatahi, te tono o te taiaho-rua-rua i roto i te waenganui-infrared (waenganui- IR) ZnGeP2 (ZGP) whatu parametric oscillator (OPO), e whakarato ana i te huarahi pono ki te whakatutuki i nga reiti tukurua teitei me nga wa poto o te nanosecond pulse mo nga OPO ZGP-waenganui-infrared.Ko te mana whakaputa toharite ko 15 W, e rite ana ki te roanga o te pupuhi o te 4.9 ns me te tere tukurua o te 100 kHz.
Ka whakaatuhia e matou mo te wa tuatahi te whakatipuranga o te octave-awhiti-waenganui-pokaraka ma te whakamahi i te karaihe kore raina BGSe.Ko te punaha laser Cr:ZnS e tuku ana i te 28-fs i te roangaru o waenganui o te 2.4 µm ka whakamahia hei puna papu, e peia ana te whakaputanga rerenga rereke-roto i roto i te karaihe BGSe.Ko te mutunga mai, kua riro mai he aunui honohono waenga-infrared mai i te 6 ki te 18 µm.E whakaatu ana ko te karaihe BGSe he rauemi whaihua mo te aunui, he iti-hurihuri te whakatipuranga waenga-pokarekare ma te huringa ki raro me nga puna papu femtosecond.
1.53 W katoa-totoka-katoa nanohaakona i whakapoipoihia waenganui-pokarere laser i te 6.45 µm
