Noi o Neodymium Ion Concentration Gradient YAG Crystal ma End-Pumped Laser Technology

ʻAʻole hiki ke hoʻokaʻawale ʻia ka hoʻomohala wikiwiki ʻana o ka ʻenehana laser mai ka hoʻomaikaʻi nui ʻana o nā laser semiconductor, nā mea aniani artificial a me nā mea hana. I kēia manawa, ke ulu nei ke kahua o ka semiconductor a me ka ʻenehana laser solid-state. I mea e hoʻomaopopo hou ai i ke kūlana o ka noiʻi ʻepekema a me nā noi palekana palekana aupuni e pono ai ka semiconductor ikaika a me ka ʻenehana laser solid-state, a me ka hoʻolaha ʻana i nā hoʻololi hoʻonaʻauao ma luna a me lalo o ka ʻenehana laser, e paʻa ka Chinese Society of Optical Engineering i ka "Advanced Semiconductor, Solid-State Laser Technology and Application Exchange Conference" i 2024 e hana i nā noi hohonu, nā ʻenehana a me ka holomua o ka wā e hiki mai ana. semiconductors a me nā lasers solid-state.

Ma kēia hālāwai, ua hōʻike ka luna o kā mākou hui, ʻo Zhang Jianjun, i ka noi oneodymium ion concentrationgradientYAG anianima ka ʻenehana laser pauku. Loaʻa i nā lasers solid-state diode-pumped (DPSSL) nā mea maikaʻi o ka hana kiʻekiʻe, ka maikaʻi o ka beam kiʻekiʻe, ke kūpaʻa maikaʻi, ka hana paʻa, a me ke ola lōʻihi. Hoʻohana ʻia ka paila diode i nā lasers Nd:YAG i ʻelua ʻano hoʻoheheʻe: ʻaoʻao ʻaoʻao (i ʻōlelo ʻia ʻo ka ʻaoʻao ʻaoʻao) a me ka pau ʻana (i kapa ʻia ʻo ka pau ʻana o ka pauma).

Hoʻohālikelike ʻia me ka hoʻoheheʻe ʻana i ke kukui a me ka ʻaoʻao semiconductor pumping, ʻoi aku ka maʻalahi o ka hoʻokō ʻana i ke ʻano hoʻohālikelike ma waena o ka puhi kukui a me ke kukui oscillating i ka lua laser. Eia kekahi, ʻo ka nānā ʻana i ka beam pump i kahi liʻiliʻi liʻiliʻi ma mua o ke koʻokoʻo laser hiki ke kaupalena i ka helu o nā ʻano i loko o ka lua a hoʻomaikaʻi maikaʻi i ka maikaʻi o ka beam. I ka manawa like, loaʻa iā ia nā pono o ka hoʻolālā compact, ka paepae laser haʻahaʻa, a me ka hana kiʻekiʻe. Ua hōʻike ʻia nā haʻawina ʻo ka hoʻopau ʻana i ka pauma ʻana i kēia manawa ke ala ʻoi aku ka maikaʻi o ka hoʻomake ʻana.
