Te Whakamahinga o te Neodymium Ion Concentration Gradient YAG Crystal i roto i te Hangarau Taiaho Whakamutunga-Mama

Ko te whakawhanaketanga tere o te hangarau laser kaore e taea te wehe mai i te whakapainga nui o nga laser semiconductor, nga taonga karaihe artificial me nga taputapu. I tenei wa, kei te tipu haere te mara o te hangarau semiconductor me te hangarau laser solid-state. I roto i te tikanga ki te mohio atu te mana o te rangahau pūtaiao tapahi-mata me te tono haumarutanga tiaki motu hiahia o te kaha teitei semiconductor me te hangarau taiaho totoka-kāwanatanga, me te whakatairanga whakawhitinga mātauranga i roto i te whakarunga, me te whakararo o te hangarau taiaho, te Hainamana Society o Optical Engineering ka mau te "Semiconductor Arā, Solid-State Taiaho Hangarau me te Huihuinga Taupānga Whakawhitiwhiti" i roto i te 2024 ki te whakahaere i roto i-hohonu tono, te ahunga whakamua me te ahunga whakamua i runga i te ahunga whakamua i runga i te hangarau. Semiconductors me lasers āhua totoka.

I tenei hui, i korero to matou tiamana kamupene, a Zhang Jianjun, mo te tono ote kukū katote neodymiumrōnakiYAG tioatai roto i te mutunga-pump laser technology.Solid-state lasers are usually optically pumped, and there are two main types of pumping ways: rama papu me te diode papu. Ko nga lasers solid-state (DPSSL) te diode-pumped te painga o te tino pai, te kounga o te kurupae teitei, te pai o te pumau, te hanganga kiato, me te ora roa. E whakamahia ana te puritanga diode i roto i nga lasers Nd:YAG i roto i nga momo putunga e rua: te papu taha (e kiia ana ko te papu taha) me te pamu mutunga (e kiia ana ko te pamu mutunga).

Ki te whakatauritea ki te kumara rama me te kumara taha semiconductor, he maamaa ake te puritanga mutunga o te semiconductor ki te whakatutuki i te aratau e rite ana i waenga i te kumara marama me te rama oscillating i roto i te kohao taiaho. I tua atu, ko te arotahi i te kurupae papu ki te rahi iti ake i te rakau laser ka taea te whakaiti i te maha o nga momo momo i roto i te kohao me te pai ake te whakapai ake i te kounga kurupae. I te wa ano, kei a ia nga painga o te hanganga kiato, te paepae laser iti, me te kaha nui. Kua whakaatuhia e nga rangahau ko te paunga mutunga ko te tikanga tino pai rawa atu i tenei wa.
