Nd: YVO4
Nd: YVO4 kristaliste nimwe murwego rwohejuru rwa laser yakira kristu iriho ubu kuri diode laser yavomye leta ikomeye.Umubyimba munini wacyo uhumanya ikirere ku burebure bwumurambararo, coeffisente yo kwinjirira cyane hamwe no kwaguka kwagutse kwinshi kuri pompe yumurambararo wa pompe, laser yo hejuru yangiritse yangiritse kimwe nibintu byiza byumubiri, optique nubukanishi bituma Nd: YVO4 kristu nziza cyane kubububasha bukomeye, butajegajega kandi igiciro cyiza cya diode yavomye bikomeye-leta laseri.
Ibiranga na Porogaramu
★ Intambwe ntoya kandi ihanamye cyane
Kwishingikiriza hasi kuburebure bwa pompe
Ibinini binini byangiza imyuka yambukiranya igice
Kwinjira cyane hejuru ya pompe yagutse yumurambararo
★ Mubyukuri uniaxial kandi nini birefringence isohora lazeri
★ Kubirebire-birebire-byerekana ibisohoka no gushushanya
★ Diode laser-pomped Nd: YVO4 compact laser hamwe ninshuro zayo zikubye kabiri icyatsi kibisi, umutuku cyangwa ubururu bizaba ibikoresho byiza bya laser byo gutunganya, gutunganya ibikoresho, spekitroscopi, kugenzura wafer, kwerekana urumuri, kwisuzumisha kwa muganga, gucapa laser nibindi bikwirakwizwa cyane Porogaramu
