    Nd: YVO4 ke kristale e sebetsang hantle ka ho fetisisa ea laser bakeng sa ho pompa ha diode har'a likristale tsa morao-rao tsa laser, haholo-holo bakeng sa matla a tlase ho isa bohareng. Sena ke haholoholo bakeng sa ho monya le ho hlahisa likarolo tse fetang Nd: YAG. E kentsoe ke li-laser diode, Nd: YVO4 kristale e kentsoe ka likristale tse phahameng tsa NLO (LBO, BBO, kapa KTP) ho fetisa sehlahisoa khafetsa ho tsoa ho infrared e haufi le e tala, e putsoa kapa UV. Ts'ebetso ena ea ho aha li-lasers tsohle tse tiileng ke sesebelisoa sa laser se ka koahelang lits'ebetso tse atileng ka ho fetesisa tsa lasers, ho kenyelletsa machining, ho sebetsana le thepa, ho shebella lintho tse ngata, tlhahlobo ea wafer, lipontšo tsa mabone, tlhahlobo ea bongaka, khatiso ea laser le polokelo ea data, jj. ho bonts'itsoe hore Nd: YVO4 e thehiloeng ka diode e pompetsoeng ka lasers ea mmuso o tiileng e lula ka potlako mebarakeng eo ka tloaelo e laoloang ke li-lasers tsa metsi tse pholileng le li-lasers tse pompetsoeng ka lebone, haholoholo ha ho hlokahala moralo oa komporo le sephetho sa mofuta o mong oa bolelele ba nako.
    Nd: Melemo ea YVO4 ho feta Nd: YAG:
    • Ho phahama ka makhetlo a ka bang mahlano a maholo ho sebetsa ho feta bophara ba pompo bo pharaletseng ho pota 808 nm (ka hona, ho itšetleha ka bolelele ba pompo ea wavelength ho tlase haholo ebile ho na le tšekamelo e matla ea tlhahiso ea mofuta o le mong);
    • Karolo e kholo ea makhetlo a mararo ho feta makhetlo a mararo e kholo ho feta bokahohle ba bolelele ba 1064nm;
    • Monyako o tlase le bokhoni bo phahameng ba letsoapo;
    • Joaloka kristale e sa hlakoheng e nang le birefringence e kholo, peō e khanya haholo. 
    Lisebelisoa tsa Laser tsa Nd: YVO4:
    • Sebopeho se seng se khahlehang haholo sa Nd: YVO4, ha e bapisoa le Nd: YAG, ke coefficient ea eona e kholo ea ho monya makhetlo a 5 ho bandwidth e pharaletseng ea phallo ho potoloha 808nm peak pump pump wavelength, e lumellanang feela le maemo a li-diode tsa laser tse nang le matla a holimo tse fumanehang hajoale. Sena se bolela kristale e nyane e neng e ka sebelisoa bakeng sa laser, e lebisang tsamaisong ea laser e kopaneng haholoanyane. Bakeng sa matla a fanoeng, sena se boetse se bolela boemo bo tlase ba matla moo laser diode e sebetsang teng, ka hona e eketsa nako ea bophelo ea diode ea laser e turang. Bophara ba phallo e pharalletseng ea Nd: YVO4 e ka fihlelang makhetlo a 2.4 ho isa ho a 6.3 a Nd: YAG. Ntle le ho pompa hantle, ho boetse ho bolela mefuta e mengata ea khetho ea diode. Sena se tla thusa baetsi ba sistimi ea laser bakeng sa mamello e pharalletseng bakeng sa khetho e tlase ea litšenyehelo.
    • Nd: YVO4 kristale e na le likarolo tse kholo tse matlafatsang mochini, ka bobeli ho 1064nm le 1342nm. Ha selepe se khaola Nd: YVO4 kristale e lekang ka 1064m, e phahame makhetlo a mane ho feta ea Nd: YAG, ha 1340nm karolo ea sefapano e hlohlellelitsoeng e le kholo ho feta makhetlo a 18, e lebisang ts'ebetsong ea CW e fetang ka botlalo Nd: YAG ka 1320nm. Tsena li etsa hore laser ea Nd: YVO4 e be bonolo ho boloka mochini o matla o le mong ho li-wavelength tse peli.
    • Sebopeho se seng sa bohlokoa sa Nd: YVO4 lasers ke, hobane ke uniaxial ho fapana le symmetry e phahameng ea li-cubic joalo ka Nd: YAG, e hlahisa feela laser e nang le linearly, ka hona e qoba litlamorao tse sa rateheng tsa birefringent phetohong ea maqhubu. Le ha nako ea bophelo ba Nd: YVO4 e le khuts'oane ka makhetlo a 2.7 ho feta ea Nd: YAG, ts'ebetso ea eona ea letsoapo e ntse e le holimo haholo bakeng sa moralo o nepahetseng oa laser cavity, ka lebaka la pompo ea eona e phahameng ea pompo.
