Nd: YVO4 nuburyo bwiza bwa laser yakira kristu yo kuvoma diode hagati yubucuruzi bwa lazeri yubucuruzi, cyane cyane kubucucike buke kugeza hagati.Ibi ahanini kubiranga no gusohora ibintu birenze Nd: YAG.Yavomwe na laser diode, Nd: YVO4 kristal yashizwemo hamwe na kristu ya NLO yo hejuru (LBO, BBO, cyangwa KTP) kugirango ihindurwe-ihinduranya ibisohoka biva hafi ya infragre ikagera ku cyatsi, ubururu, cyangwa UV.Uku kwishyiriraho kubaka lazeri zose zikomeye ni igikoresho cyiza cya laser gishobora gukwirakwiza porogaramu zikoreshwa cyane, harimo gutunganya, gutunganya ibikoresho, spekitroscopi, kugenzura wafer, kwerekana urumuri, gusuzuma ubuvuzi, gucapa lazeri, no kubika amakuru, nibindi. Byerekanwe ko Nd: YVO4 ishingiye kuri diode yavomye ibyuma bikomeye bya leta bigenda byigarurira amasoko gakondo yiganjemo ion ikonjesha amazi ya lazeri hamwe na lazeri yapompe amatara, cyane cyane mugihe hagomba gukenerwa igishushanyo mbonera hamwe n’ibisubizo birebire-byerekana uburyo bumwe.
Nd: Ibyiza bya YVO4 kurenza Nd: YAG:
• Mugihe kingana ninshuro eshanu nini zo kwinjirira neza hejuru yumurongo mugari wa pompe hafi 808 nm (kubwibyo rero, biterwa no kuvoma uburebure bwumurongo uri hasi cyane kandi ni imyumvire ikomeye yo gusohora uburyo bumwe);
• Ninshuro eshatu nini nini zitera imyuka ihumanya ikirere ku burebure bwa 1064nm;
• Hasi ya lasing ntarengwa kandi ihanamye cyane;
• Nka kristu ihuriweho hamwe na birefringence nini, imyuka ihumanya ni umurongo umwe gusa.
Ibyiza bya Laser ya Nd: YVO4:
• Imwe mu mico ishimishije ya Nd: YVO4 ni, ugereranije na Nd: YAG, coefficente yayo yikubye inshuro 5 mu kwaguka kwagutse kwagutse kwagutse kangana na 808nm ya pompe yumurambararo wa pompe, ihuye gusa nuburinganire bwa diode ya diode nini cyane iboneka muri iki gihe.Ibi bivuze ko kristu ntoya ishobora gukoreshwa kuri laser, biganisha kuri sisitemu yoroheje.Ku mbaraga zitangwa zisohoka, ibi bivuze kandi imbaraga zo hasi aho laser diode ikorera, bityo ikongerera ubuzima bwa diode ihenze.Umuyoboro mugari wa Nd: YVO4 ushobora kugera kuri 2,4 kugeza kuri 6.3 ugereranije na Nd: YAG.Usibye kuvoma neza, bisobanura kandi intera nini yo guhitamo diode yihariye.Ibi bizafasha abakora sisitemu ya laser kugirango bihangane muguhitamo ibiciro bike.
• Nd: Crystal YVO4 ifite imyuka minini itera imyuka ihumanya ikirere, haba kuri 1064nm na 1342nm.Iyo a-axis yaciye Nd: YVO4 kristaliste ikubita kuri 1064m, irikubye inshuro 4 kurenza iya Nd: YAG, mugihe kuri 1340nm igice cyashizwe hejuru cyikubye inshuro 18, biganisha kumikorere ya CW irusha rwose Nd: YAG kuri 1320nm.Ibi bituma Nd: YVO4 laser byoroha kugumana umurongo umwe ukomeye wohereza imyuka ibiri.
• Indi mico yingenzi ya Nd: YVO4 laseri ni, kubera ko ari uniaxial aho kuba impuzandengo ya cubic nka Nd: YAG, isohora gusa lazeri ikomatanyirijwe hamwe, bityo ikirinda ingaruka zitifuzwa ku guhinduka kwinshi.Nubwo ubuzima bwa Nd: YVO4 bugufi inshuro 2,7 ugereranije nubwa Nd: YAG, imikorere yacyo irashobora kuba ndende cyane kugirango habeho igishushanyo mbonera cya laser, kubera ubushobozi bwa pompe ikora neza.
