Ngā Pūrongo - He aha mātou i whakamahi ai i te tioata Nd: YAG hei reo whakanui i roto i te taiaho DPSS?

Ohauru ki ā Mātou Pāpāho Hapori mō te Pou Whakaoho

He aha te Waenga Whiwhi Taiaho?

He rauemi te reo whakanui taiaho e whakanui ana i te mārama mā te tukunga whakaohooho. Ina whakaohokia ngā ngota, ngā ngota rānei o te reo ki ngā taumata pūngao teitei ake, ka taea e rātou te tuku i ngā irahiko o tētahi roangaru motuhake ina hoki ki tētahi āhua pūngao iti iho. Mā tēnei tukanga ka whakanui ake i te mārama e whiti ana i roto i te reo, he mea nui tēnei ki te mahi taiaho.

He aha te Waenga Whakanui Noa?

Ka taea te rerekē te momo whakanui, tae atu kingā hau, ngā wai (ngā tae), ngā mea totoka(ngā tioata, ngā karāhe rānei kua whakaranua ki ngā katote konganuku onge, ki ngā katote konganuku whakawhiti rānei), me ngā haurua-ā-ira.Ngā taiaho āhua-totoka, hei tauira, he maha ngā tioata e whakamahia ana pērā i te Nd: YAG (Neodymium-doped Yttrium Aluminum Garnet) me ngā karāhe kua whakaranua ki ngā huānga whenua-onge. Ka whakamahia e ngā taiaho tae ngā tae waro kua rewa i roto i ngā whakarewa, ā, ka whakamahia e ngā taiaho hau ngā hau, ngā ranunga hau rānei.

Ngā rerekētanga i waenga i te Nd (Neodymium), te Er (Erbium), me te Yb (Ytterbium) hei reo whakanui

e pā ana ki ō rātou roangaru tukunga, ngā tikanga whakawhiti pūngao, me ngā tono, inā koa i roto i te horopaki o ngā rauemi taiaho kua tāpirihia.

Ngā Roangaru Tukunga:

- Er: Ko te tikanga ka tukuna e te erbium he 1.55 µm, kei roto i te rohe haumaru mō ngā kanohi, ā, he tino whai hua mō ngā tono whakawhitiwhiti kōrero nā te iti o te ngaronga o ngā muka whatu (Gong et al., 2016).

- Yb: He maha ngā wā ka tukuna e te Ytterbium te hiko i waenga i te 1.0 ki te 1.1 µm, ā, he pai mō ngā momo whakamahinga maha, tae atu ki ngā taiaho me ngā whakakaha hiko teitei. He maha ngā wā ka whakamahia a Yb hei whakaohooho i te Er hei whakarei ake i te whai huatanga o ngā taputapu kua tāpirihia ki te Er mā te whakawhiti i te pūngao mai i te Yb ki te Er.

- Nd: Ko ngā rauemi kua tāpirihia ki te neodymium ka tukuna te hiko tata ki te 1.06 µm. Hei tauira, he rongonui te Nd:YAG mō tōna whai huatanga, ā, he whānuitia te whakamahinga i roto i ngā taiaho ahumahi me te hauora (Y. Chang et al., 2009).

Ngā Tikanga Whakawhiti Pūngao:

- Te whakakotahitanga o Er me Yb: He pai te whakakotahitanga o Er me Yb i roto i te reo manaaki hei whakarei ake i te tukunga i te awhe 1.5-1.6 µm. He mahi a Yb hei whakaohooho whai hua mō Er mā te mimiti i te mārama papu me te whakawhiti i te pūngao ki ngā iona Er, ka hua ake he tukunga kua whakanuia i roto i te roopu whakawhitiwhiti kōrero. He mea nui tēnei whakawhiti pūngao mō te whakahaere o ngā whakakaha muka kua whakakotahitia ki Er (EDFA) (DK Vysokikh et al., 2023).

- Nd: Kāore e hiahiatia ana e te Nd he matū whakaohooho pēnei i te Yb i roto i ngā pūnaha Er-doped. Ko te whai huatanga o te Nd ka ahu mai i tana mimiti tika o te mārama papu me te tukunga i muri mai, ka waiho hei reo whakanui taiaho māmā me te whai hua.

Ngā tono:

- Āe:E whakamahia ana i roto i ngā whakawhitiwhiti kōrero nā te mea he 1.55 µm te nui o te tukunga, e rite ana ki te matapihi ngaronga iti rawa o ngā muka whatu silica. He mea nui ngā reo whakanui Er-doped mō ngā whakakaha whatu me ngā taiaho i roto i ngā pūnaha whakawhitiwhiti whatu muka tawhiti.

- Yb:He maha ngā whakamahinga e whakamahia ana i roto i ngā tono mana-teitei nā tōna hanganga hiko māmā noa iho e āhei ai te papu diode whai hua me te putanga mana teitei. Ka whakamahia hoki ngā rauemi Yb-doped hei whakarei ake i te mahi a ngā pūnaha Er-doped.

- NdHe tino pai mō ngā momo mahi maha, mai i te tapahi ahumahi me te whakarewa ki ngā taiaho hauora. He mea nui ngā taiaho Nd:YAG mō tō rātou whai huatanga, tō rātou kaha, me te maha o ngā whakamahinga.

He aha mātou i whiriwhiri ai i te Nd:YAG hei reo whakanui i roto i te taiaho DPSS?

Ko te taiaho DPSS he momo taiaho e whakamahi ana i tētahi reo whakanui āhua-totoka (pēnei i te Nd: YAG) e pupuhihia ana e tētahi taiaho haurua-irahiko. Mā tēnei hangarau ka taea te hanga taiaho kiato, whai hua hoki, ka taea te whakaputa hihi kounga teitei i roto i te whānuitanga e kitea ana-ki-te-whero. Mō tētahi tuhinga taipitopito, whakaarohia te rapu i roto i ngā pātengi raraunga pūtaiao rongonui, i ngā kaiwhakaputa rānei mō ngā arotake whānui mō te hangarau taiaho DPSS.

He maha ngā take e whakamahia ai te Nd:YAG hei reo whakanui i roto i ngā kōwae taiaho e pupuhihia ana e te haurua-irahiko, e ai ki ngā rangahau maha:

1. Teitei o te Whai Hua me te Putanga ManaI whakaatuhia e te hoahoa me ngā whakatauira o tētahi waeine taiaho Nd:YAG e papua ana e te taha o te diode te tino whai huatanga, me te taiaho Nd:YAG e papua ana e te taha o te diode e whakarato ana i te mana toharite mōrahi o te 220 W me te pupuri tonu i te kaha pumau mō ia pao i roto i te whānuitanga auau whānui. E tohu ana tēnei i te tino whai huatanga me te kaha mō te putanga mana teitei o ngā taiaho Nd:YAG ina papua e ngā diode (Lera et al., 2016).
2. Ngāwari me te Pono o te WhakahaereKua whakaaturia te whai huatanga o ngā uku Nd:YAG ki te mahi i ngā roangaru rerekē, tae atu ki ngā roangaru haumaru-kanohi, me te whai huatanga whatu-ki-whatu teitei. E whakaatu ana tēnei i te maha o ngā mahi me te pono o Nd:YAG hei reo whakanui i roto i ngā tono taiaho rerekē (Zhang et al., 2013).
3. Te Roa o te Ora me te Kounga o te KurupaeI roto i ngā rangahau mō tētahi taiaho Nd:YAG tino whai hua, he mea papu-diode, i whakanuia tōna roa me tōna mahi pumau, e whakaatu ana i te pai o te Nd:YAG mō ngā tono e hiahia ana ki ngā pūtake taiaho pumau me te pono. I kōrerohia e te rangahau te mahi roa me te neke atu i te 4.8 x 10^9 pupuhi me te kore he kino whatu, me te pupuri i te kounga hihi pai rawa atu (Coyle et al., 2004).
4. Mahi Ngaru-tonu Tino Pai:Kua whakaatuhia e ngā rangahau te tino whai huatanga o te mahi ngaru-tonu (CW) o ngā taiaho Nd:YAG, e whakaatu ana i tōna whai huatanga hei reo whakanui i roto i ngā pūnaha taiaho papu-diode. Kei roto i tēnei ko te whakatutuki i ngā whai huatanga tahuritanga whatu teitei me ngā whai huatanga pari, e whakaatu ana i te pai o te Nd:YAG mō ngā tono taiaho whai hua teitei (Zhu et al., 2013).

Mā te huinga o te tino pai o te mahi, te putanga hiko, te ngāwari o te mahi, te pono, te roa o te ora, me te kounga hihi tino pai, ka waiho a Nd:YAG hei reo whakanui pai i roto i ngā kōwae taiaho e papuhia ana e te haurua-ira mō te whānuitanga o ngā tono.
