    Basic zvivakwa

    Nd: YVO4 ndiyo inonyanya kushanda laser inomira kristaro ye diode kupomba pakati pazvino tengesa laser makristasi, kunyanya, yepasi kusvika pakati pesimba masimba. Izvi zvinonyanya kuitisa uye kuburitsa maficha anodarika Nd: YAG. Yakapomerwa ne laser diode, Nd: YVO4 kristaro yakaverengerwa neakakwira NLO coefficient makristasi (LBO, BBO, kana KTP) ku frequency-chinja zvinobuda kubva padyo infrared kune girini, bhuruu, kana kunyange UV. Uku kusanganisa kuvaka ese akasimba ehurumende lasers chishandiso chakanakisa che laser chinogona kuvhara mashandisirwo akapararira eelaser, kusanganisira machining, kugadzirisa zvinhu, kutarisisa, kuongorora chitete, kuratidzwa kwechiedza, kurapwa kwekurapa, kudhinda kwemalaser, uye kuchengetedza data, nezvimwewo. zvakaratidzirwa kuti Nd: YVO4 based diode pumped solid state lasers vari kukurumidza kutora misika yakajairwa inotungamirwa nemvura-yakatonhorera ion lasers uye mwenje-pumped lasers, kunyanya kana compact dhizaini uye imwechete-yenguva refu-nzira nzira zvinobuda.
    Nd: YVO4 zvakanakira kupfuura Nd: YAG:
    • Yakakwira zvakapetwa kanokwana kuita kashanu kukura kwakanyanya kunoshanda pamusoro penzvimbo yakakura yekupomba yakatenderedza 808 nm (nekudaro, kutsamira pakupomba wavelength kwakadzikira kwazvo uye kwakasimba maitiro kune imwechete nzira kuburitsa);
    • Yakakura seanopetwa katatu akakurudzira kusvibiswa muchikamu chepakati pakureba kwemarefu e1064nm;
    • Chidziro chepasi chakadzikira uye kugona kwepamusoro;
    • Sekristaro isina uniaxial ine birefringence hombe, kubuda kwacho kwakangosiyana-siyana. 
    Laser Zvivakwa zveNd: YVO4:
    • Imwe yehunhu hunokwezva paNd: YVO4 iri, kana ichienzaniswa naNd: YAG, ayo mashanu kakapetwa ekuti akwane coefficient muhupamhi hwekuwedzera bandwidth kutenderedza iyo 808nm peak pombi wavelength, iyo inongowirirana neyero yemasimba epamusoro emagetsi laser diode aripo parizvino. Izvi zvinoreva kristaro diki iyo inogona kushandiswa kune iyo laser, inotungamira kune yakawanda compact laser system. Kune rakapihwa simba rekubuda, izvi zvakare zvinoreva yepasi simba rezinga pane iyo laser diode inoshanda, nokudaro ichiwedzera hupenyu hwese hweinodhura laser diode. Iyo yakazara yekuwedzera bandwidth yeNd: YVO4 iyo inogona kusvika 2.4 kusvika 6.3 nguva iyo yaNd: YAG. Kunze kwepombi inoshanda zvakanyanya, zvinoreva zvakare huwandu hwakawanda hwesarudzo yedhiodhi yakatarwa. Izvi zvichave zvinobatsira kune laser system vanogadzira yekuwedzera kuregerera kune yakaderera mutengo sarudzo.
    Nd: YVO4 kristaro ine hukuru hwakasimudzira emission-zvikamu, zvese pa1064nm uye 1342nm. Kana a-axis yakatemwa Nd: YVO4 kristaro inodzika pa1064m, ingangoita kakapetwa ka4 pane iyo yaNd: YAG, nepo pa1340nm chikamu chakasimudzwa chakakura zvakapetwa ka18, zvinotungamira kuCW oparesheni yakanyanyisa kuita Nd: YAG pa1320nm. Izvi zvinogadzira Nd: YVO4 laser ive nyore kuchengetedza yakasimba imwechete mutsara kuburitsa pane maviri wavelengths.
    • Humwe hunhu hwakakosha hwaNd: YVO4 lasers ndeye, nekuti ndeye uniaxial pane kuenzana kwakayana kwe cubic saNd: YAG, inongoburitsa yakasarudzika polarized laser, nokudaro ichidzivirira isingadiwe birefringent mhedzisiro pane iyo frequency kutendeuka. Kunyangwe iyo hupenyu hwese hwaNd: YVO4 ingangoita 2.7 yakapfupika pane iyo yaNd: YAG, kugona kwayo kwekutsvedza kunogona kunge kuchiri kwakanyanya kugadzirwa kwakakodzera kwe laser mhango, nekuda kwayo kwepombi yepamusoro kuwanda kwekuita.
