    Nd:YVO4 ʻo ia ka ʻoi aku ka maikaʻi loa o ka hoʻokipa laser kristal no ka hoʻoheheʻe ʻana i ka diode i waena o nā kristal laser kalepa o kēia manawa, ʻoi loa, no ka haʻahaʻa haʻahaʻa a waena.ʻO kēia ka mea nui no kona absorption a me ka hoʻokuʻu ʻana i nā hiʻohiʻona ma mua o Nd:YAG.Pumi ʻia e nā laser diodes, Nd: YVO4 crystal ua hoʻohui ʻia me nā kristal coefficient NLO kiʻekiʻe (LBO, BBO, a i ʻole KTP) e hoʻololi pinepine i ka puka mai ka infrared kokoke i ka ʻōmaʻomaʻo, uliuli, a i ʻole UV.ʻO kēia hoʻohui ʻana e kūkulu i nā laser mokuʻāina paʻa a pau he mea hana laser maikaʻi loa e hiki ke uhi i nā noi ākea loa o nā lasers, me ka machining, ka hoʻoili waiwai, spectroscopy, wafer inspection, light displays, medical diagnostics, laser printing, and data storage, etc. ua hōʻike ʻia ʻo Nd: YVO4 based diode pumped solid state lasers e noho wikiwiki nei i nā mākeke i hoʻomalu ʻia e nā lasers ion-cooled wai a me nā lasers lamp-pumped, ʻoi aku ka nui o ka wā e koi ʻia ai ka hoʻolālā paʻa a me nā huahana hoʻokahi-longitudinal-mode.
    Nd: Nā mea maikaʻi o YVO4 ma mua o Nd:YAG:
    • E like me ke kiʻekiʻe ma kahi o ʻelima mau manawa ʻoi aku ka maikaʻi o ka absorption ma luna o ka bandwidth pumping ākea a puni 808 nm (no laila, ʻoi aku ka haʻahaʻa o ka hilinaʻi ʻana i ka lōʻihi o ka hawewe a me ka manaʻo ikaika i ka puka hoʻokahi mode);
    • E like me ka nui e like me ekolu manawa nui i ho'oulu 'ia emission cross-section ma ka lasing wavelength o 1064nm;
    • ʻO ka paepae lasing haʻahaʻa a ʻoi aku ka maikaʻi o ka slope;
    • E like me ke aniani uniaxial me ka birefringence nui, ka hoʻokuʻu ʻana he linearly polarized wale nō.
    Nā Pono Laser o Nd:YVO4:
    • 'O kekahi 'ano u'i o Nd: YVO4 'o ia, ke ho'ohālikelike 'ia me Nd:YAG, kona 5 manawa nui o ka absorption coefficient i loko o ka bandwidth absorption ākea a puni ka 808nm peak pump ka lō'ihi o ka hawewe, e like me ka ma'amau o ka mana ki'eki'e laser diodes i kēia manawa.ʻO kēia ke ʻano he aniani liʻiliʻi i hiki ke hoʻohana ʻia no ka laser, e alakaʻi ana i kahi ʻōnaehana laser paʻa.No ka mana hoʻopuka i hāʻawi ʻia, ʻo ia hoʻi kahi pae mana haʻahaʻa kahi e hana ai ka diode laser, no laila e hoʻolōʻihi i ke ola o ka diode laser pipiʻi.ʻO ka bandwidth absorption ākea o Nd: YVO4 hiki ke hiki i ka 2.4 a i ka 6.3 manawa o Nd: YAG.Ma waho aʻe o ka ʻoi aku ka maikaʻi o ka pumping, ʻo ia hoʻi kahi ākea ākea o ke koho o nā kikoʻī diode.E kōkua kēia i nā mea hana ʻōnaehana laser no ka hoʻomanawanui ākea no ke koho haʻahaʻa haʻahaʻa.
    • Nd: YVO4 crystal he nui ka hoʻoulu ʻia o ka hoʻokuʻu ʻana i nā ʻāpana keʻa, ma 1064nm a me 1342nm.Ke ʻoki ʻia ka axis Nd: YVO4 crystal lasing ma 1064m, ʻoi aku ia ma kahi o 4 mau manawa kiʻekiʻe ma mua o ko Nd:YAG, ʻoiai ma 1340nm ʻo 18 mau manawa ka nui o ke keʻa i hoʻoulu ʻia, e alakaʻi ana i kahi hana CW i ʻoi aku ma mua o Nd:YAG. ma 1320nm.ʻO kēia ka mea e maʻalahi ai ka laser Nd: YVO4 e mālama i kahi hoʻokuʻu laina ikaika ma nā hawewe ʻelua.
    • Kekahi ano nui o Nd: YVO4 lasers mea, no ka mea, he uniaxial ma mua o ka kiʻekiʻe symmetry o cubic e like me Nd:YAG, emits wale i ka linearly polarized laser, pela e pale aku undesired birefringent hopena ma ka alapine hoohuli.ʻOiai ʻo ke ola o Nd: YVO4 ma kahi o 2.7 manawa pōkole ma mua o Nd:YAG, hiki ke kiʻekiʻe ke kiʻekiʻe o kona slope pono no ka hoʻolālā kūpono o ka lua laser, no ka mea kiʻekiʻe o ka nui o ka pump quantum efficiency.
