Taiaho kikorangi auau-kotahi mana-teitei 457nm

457nm te mana-teitei auau-kotahirēseri kikorangi
Te hoahoa ara whatu o te taiaho kikorangi auau-kotahi mana-teitei 457nm me te auau-kotahi
Ko te pūtake papu e whakamahia ana he huinga diode taiaho muka-hono 30 W. Tuarua, ka tīpakohia he resonator mowhiti mō te kōwhiringa aratau. Ka papuhia te mata pito ki te karaihe yttrium vanadate (Nd:YVO4) Nd3+-doped 5 mm te roa me te kukū o te 0.1%. Kātahi, mā roto i te kōhao karaihe lithium triborate (LBO) momo-I, ka whakaputahia te harmonic tuarua hei whakatutuki i te auau-kotahi mana-teitei 457nm.rēseriputanga. Ina 30 W te mana papu, ko te mana putanga o te taiaho auau-kotahi 457nm ko 5.43 W, ko te roangaru pokapū ko 457.06 nm, ko te pai o te tahuritanga mārama-ki-mārama ko 18.1%, ā, ko te pumau mana i roto i te 1 hāora ko 0.464%. Ka mahi te taiaho 457nm i roto i te aratau taketake i roto i te resonator. Ko ngā āhuatanga kounga hihi i te taha o te ahunga x me te y ko 1.04 me 1.07, ā, ko te porowhita o te ira mārama ko 97%.

Whakaahuatanga o te ara whatu o te mārama kikorangi mana-tiketiketaiaho auau-kotahi
Ka whakamahia e te pūtake papu he hononga muka whatudiode taiaho haurua-irahe rarangi me te roangaru pokapū o te 808 nm, te mana putanga tonu o te 30 W, me te diameter matua muka o te 400 μm, me te kōhao tau o te 0.22.
Ka whakakorikoria te mārama papu, ka arotahihia mā roto i ngā karāhe plano-convex e rua me te roa arotahi o te 20 mm, kātahi ka tau ki runga i tekaraihe taiahoKo te tioata taiaho he tioata Nd:YVO4 3 mm × 3 mm × 5 mm me te kukū tāpiringa o te 0.1%, me ngā kiriata ārai-whakaata 808 nm me te 914 nm kua whakatakotoria ki ngā pito e rua, ā, kua takaihia te tioata ki te pepa konumohe indium ka whakanohoia ki roto i tētahi taputapu whakapiri parahi. Ko te pāmahana o te taputapu whakapiri parahi he mea whakahaere tika mā te pouaka whakamatao haurua-ira, ā, kua whakatakotoria ki te 15℃.
Ko te resonator he kōhao mowhiti whakaata-whā i titoa mai i te M1, M2, M3, me te M4.
He whakaata papatahi te M1 me ngā kiriata ārai-whakaata 808 nm, 1064 nm, me te 1342 nm (R<0.05%), me te kiriata whakaata katoa 914 nm (R>99.8%); he whakaata putanga papatahi te M4 me te kiriata whakaata katoa 914 nm (R>99.8%), 457 nm me te 1064 nm, 1342 nm ngā kiriata ārai-whakaata (R<0.02%); he whakaata papatahi-piko te M2 me te M3 me te radius piko o r = 100 mm, me ngā kiriata ārai-whakaata 1064 nm me te 1342 nm (R<0.05%) i runga i te papatahi me ngā kiriata whakaata katoa 914 nm me te 457 nm (R>99.8%) i runga i te mata kōpiko.
Ko te pereti haurua-ngaru me te tioata TGG kua whakanohoia ki roto i te papa aukume he kiriata ārai-whakaata 914 nm (R<0.02%). Mā te whakauru i tētahi taputapu whatu kotahi-angihanga i titoa mai i te TGG me te pereti haurua-ngaru, ka akiakihia te taiaho kia rere kotahi-angihanga i roto i te porowhita whakakoi, kia mau ai te mahi a te taiaho i roto i te āhua auau-kotahi. He wahi paerewa te FP he matotoru o te 2 mm, he whakaata taha-rua kua pania o te 50%, ā, ka mahi i te whakawhāiti tuarua o te mahi auau-kotahi o te taiaho i roto i te kōhao. Ka tīpakohia te tioata LBO hei tioata takirua auau, he rahi o te 3 mm × 3 mm × 15 mm, ā, kua pania ki ngā kiriata ārai-whakaata 914 nm me te 457 nm (R<0.02%), me te taurite ā-wāhanga momo-I, koki tapahi θ = 90°, φ = 21.9°.
