    Nd: YVO4 o le sili lelei leisa talimalo talo tioata mo diode pamuina i totonu o le taimi nei fefaatauaiga leisa tioata, aemaise lava, mo maualalo i le ogatotonu mamafa density. E mafua lea mo lona mitiia ma faʻamalamalamaina foliga sili atu Nd: YAG. Faʻapipiʻiina e le diodes, Nd: ua faʻaaogaina le tioata a le YVO4 ma tioata maualuga o le coofficient NLO (LBO, BBO, poʻo le KTP) e faʻasolosolo ona sifi le galuega faʻatino mai le latalata atu i le lanumeamata, lanumoana, poʻo le UV. Lenei tuʻufaʻatasia e fausia uma mautu malo tulaga lasers o se sili lelei leisa mea faigaluega e mafai ona ufiufi ai le sili ona lautele faʻaogaina o lasers, e aofia ai masini, mea gaosi, spectroscopy, lalaga asiasiga, faʻaali malamalama, fomaʻi diagnostics, leisa lolomiga, ma faʻamaumauga teuina, ma isi. ua faʻaalia o Nd: YVO4 faʻavae diode pamu lasers tulaga malo o loʻo vave nofoia le maketi masani faʻataʻitaʻia e le vai-faʻaliliina ion lasers ma lamepa-pamu lasers, aemaise lava pe a puʻupuʻu mamanu ma tasi-longitudinal-mode galuega faatino e manaʻomia.
    Nd: mea lelei a le YVO4 nai lo Nd: YAG:
    • E tusa o le lima taimi lapoʻa faʻaalu lelei lelei i luga o le lautele pamuina bandwidth i le 808 nm (o le mea lea, o le faʻamoemoe i le pamuina wavelength e matua maualalo ma se malosi foliga i le tasi auala faiga);
    • E tusa lona lapoʻa ma le faʻatolu taimi lapoʻa na faʻaosofia ai le faʻasologa o le faʻasologa i le tau o le 1064nm lasing;
    • Lago maualalo faitotoʻa ma maualuga tifato lelei;
    • I le avea ai o se tioata uniaxial ma le tele paʻu, o le faʻamatuʻuina ua na o se linearly polarized. 
    Leisa Faʻaogaina o Nd: YVO4:
    • Tasi le sili ona lalelei uiga o Nd: YVO4 o, faʻatusatusa ma Nd: YAG, lona 5 faʻatele lapoʻa faʻaaogaina i totonu o le lautele lautele taliaina bandwidth i tafatafa o le 808nm tumutumu pamu wavelength, lea e tutusa lelei ma le faʻataʻitaʻiga o le maualuga paoa leisa diode o loʻo avanoa nei. O lona uiga o se tamaʻi tioata e mafai ona faʻaaogaina mo le leisa, e oʻo atu ai i le sili atu ona puʻupuʻu leisa system. Mo le tuuina atu mana galuega faatino, o lona uiga foi o se maualalo paoa tulaga lea o loo faagaoioia le leisa diode, faapea faalautele ai le olaga atoa o le taugata leisa diode. O le lautele lautele faʻasalalau bandwidth o Nd: YVO4 lea e ono oʻo atu i le 2.4 i le 6.3 taimi nai lo Nd: YAG. E le gata i le lelei pamuina, o lona uiga foi o le lautele lautele o filifiliga o diode auiliili. Lenei o le a fesoasoani i leisa faiga faia mo lautele lautele faapalepale mo maualalo tau filifiliga.
    • Nd: O le tioata a le YVO4 e tele atu na faʻaosofia ai faʻasologa o vaega, i le 1064nm ma le 1342nm. A tipiina se-au Nd: YVO4 tioata lasing i le 1064m, e tusa ma le 4 taimi maualuga atu nai lo Nd: YAG, ae i le 1340nm o le stimulated koluse-vaega e 18 taimi tele atu, lea e tau atu ai i le CW faʻagaioiga sili atu le lelei Nd: YAG i le 1320nm. Nei faia Nd: YVO4 leisa e faigofie e faʻatumauina le malosi tasi laina laina i le lua wavelengths.
    • O le isi taua uiga o Nd: YVO4 lasers e, aua o se uniaxial nai lo le maualuga symmetry o cubic pei o Nd: YAG, na o le faʻalauiloaina o se laina linear polarized leisa, o lea aloese mai le le manaʻomia aafiaga birefringent i luga o le taimi o suiga. E ui lava o le soifuaga o Nd: YVO4 e tusa ma le 2.7 taimi e puʻupuʻu nai lo le Nd: YAG, o lona faʻaaogaina e mafai ona maualuga atu pea mo se ata lelei o le laser hole, ona o le maualuga o le pamu aofaʻi lelei.
