Nd: YAG — Mea Hana Laser Paʻa maikaʻi loa
Hōʻike huahana
Nd: ʻO YAG ka mea paʻa i ka laser me ka hana piha maikaʻi loa.Nd: Hoʻomoʻi ʻia nā laser YAG me ka hoʻohana ʻana i kahi flashtube a i ʻole laser diodes.
ʻO kēia kekahi o nā ʻano laser maʻamau, a hoʻohana ʻia no nā noi like ʻole.Nd: Hoʻopuka pinepine nā laser YAG i ka mālamalama me ka lōʻihi o ka nalu o 1064nm, i ka infrared.Nd: Ke hana nei nā lasers YAG ma ke ʻano pulsed a me ke ʻano hoʻomau.Pulsed Nd: Hoʻohana pinepine ʻia nā lasers YAG ma ke ʻano i kapa ʻia ʻo Q-switching mode: Hoʻokomo ʻia kahi hoʻololi optical i loko o ka lua laser e kali ana i ka hoʻohuli ʻana o ka heluna kanaka i nā ion neodymium ma mua o ka wehe ʻana.
A laila hiki i ka nalu māmā ke holo i loko o ka lua, e hoʻemi ana i ka ʻenehana laser hauʻoli i ka nui o ka heluna kanaka.Ma kēia ʻano Q-switched, ua loaʻa nā mana hoʻopuka o 250 megawatts a me ka lōʻihi o ka pulse o 10 a 25 nanoseconds.[4]Hiki ke hoʻopālua ʻia nā puʻupuʻu kiʻekiʻe no ka hoʻoulu ʻana i ke kukui laser ma 532 nm, a i ʻole harmonics kiʻekiʻe ma 355, 266 a me 213 nm.
ʻO ka Nd: YAG laser rod i hana ʻia e kā mākou hui i nā hiʻohiʻona o ka waiwai kiʻekiʻe, ka paepae laser haʻahaʻa, ka conductivity thermal maikaʻi a me ka haʻalulu wela.He kūpono ia no nā ʻano hana like ʻole (hoʻomau, pulse, Q-switch a me ke ʻano laka).
Hoʻohana maʻamau ia i nā lasers solid-state kokoke loa-infrared, pinepine pālua a me nā noi tripling pinepine, Hoʻohana nui ia i ka noiʻi ʻepekema, lapaʻau lapaʻau, ʻoihana a me nā kula ʻē aʻe.
