    Iipropathi ezisisiseko

    Nd: I-YVO4 yeyona kristale ingummangaliso ye-laser yokupompa i-diode phakathi kweekristal zorhwebo zangoku ze-laser, ngakumbi, ukuya koxinano lwamandla asezantsi ukuya embindini. Oku ikakhulu kukufakwa kunye nokukhupha amanqaku okudlula kwi-Nd: YAG. Iimpompo ngee-diode zelaser, Nd: YVO4 yikristale ifakiwe kunye ne-NLO ephezulu yokulinganisa iikristali (i-LBO, i-BBO, okanye i-KTP) yokuhambisa rhoqo isiphumo esivela kufutshane ne-infrared ukuya kuluhlaza, luhlaza okwesibhakabhaka, okanye kwi-UV. Olu fakelo lokwakha zonke ii-lasers eziqinileyo zikarhulumente sisixhobo esifanelekileyo se-laser esinokugubungela ezona zicelo zixhaphakileyo zeelaser, kubandakanya ukwenziwa kwemishini, ukuqhubekeka kwezinto, ukubonwa okubonakalayo, ukuhlolwa kokujonga, ukubonisa ukukhanya, ukuxilongwa kwezonyango, ukuprintwa kwelaser, kunye nokugcinwa kwedatha, njl. kubonisiwe ukuba i-Nd: YVO4 esekwe kwidayode eyomeleleyo e-lasers zikarhulumente zihlala ngokukhawuleza kwiimarike ngokwesiko zilawulwa nge-lasers ezipholileyo ngamanzi kunye neelas-pump lasers, ngakumbi xa uyilo olumbumbeneyo kunye nemveliso ye-longitudinal-mode.
    Nd: Izibonelelo zeYVO4 ngaphezulu kweNd: YAG:
    • Ukuphakama kangangezihlandlo ezikhulu ezihlanu zokufunxa okuthe kratya kububanzi bebhobho yokumpompa ebanzi ejikeleze i-808 nm (ke ngoko, ukuxhomekeka kubude bempompo yobude busezantsi kakhulu kwaye notyekelo olomeleleyo kwimveliso yendlela enye);
    • Inkulu kangangezihlandlo ezithathu evusa inkunkuma enqamlezileyo kwi-wavelength ye-1064nm;
    • Uthango olusezantsi kunye nokusebenza kwethambeka eliphezulu;
    • Njengekristale engavulelekanga enebirefringence enkulu, ukukhutshwa kuphela kulungelelaniswe kakuhle. 
    Iimpawu zeLaser zeNd: YVO4:
    Olona phawu luthandekayo luka-Nd: YVO4, xa kuthelekiswa no-Nd: YAG, amaxesha ayo ama-5 wokulungelelanisa ukufezekisa ubungakanani bebhendi yokufunxa ebanzi malunga ne-808nm incopho yempompo yobude, ehambelana nje nomgangatho wamandla aphezulu e-laser diode ezikhoyo ngoku. Oku kuthetha ukuba yikristale encinci enokusetyenziselwa i-laser, ekhokelela kwinkqubo ye-laser ethe kratya. Kwisiphumo samandla esinikiweyo, oku kukwathetha inqanaba lamandla asezantsi apho i-laser diode isebenza khona, oko ke kwandise ixesha lokuphila kwe-diode ebiza kakhulu ye-laser. Ububanzi bebhendi yokufunxa ebanzi ye-Nd: YVO4 enokufikelela kuma-2.4 ukuya kuma-6.3 amaxesha ka-Nd: YAG. Ngaphandle kokumpompa ngokukuko, ikwathetha uluhlu olubanzi lokhetho lweenkcukacha zediode. Oku kuya kuba luncedo kubenzi benkqubo ye-laser yokunyamezelana ngokubanzi kukhetho lweendleko eziphantsi.
    Nd: I-YVO4 yikristale inamacandelo eminqamlezo amakhulu avuselelayo, omabini e-1064nm nase-1342nm. Xa i-axis cut cut Nd: YVO4 i-crystal lasing kwi-1064m, imalunga namaxesha ama-4 aphezulu kunalawo ka-Nd: YAG, ngelixa ngo-1340nm icandelo elinqamlezileyo elivuselelweyo lingama-18 amakhulu, oko kukhokelela ekusebenzeni kwe-CW kugqibe ngokupheleleyo u-Nd: YAG kwi-1320nm. Oku kwenza i-Nd: YVO4 laser kube lula ukugcina ukukhutshwa komgca omnye oqinileyo kwii-wavelengths ezimbini.
    • Omnye umlinganiswa obalulekileyo ka-Nd: YVO4 lasers ngu, kuba yi-uniaxial endaweni yolingano oluphezulu lweetyhubhu njengo-Nd: YAG, ikhupha kuphela i-laser ehambelana nomgca, oko kuthintela iziphumo ezingafunekiyo ze-birefringent kuguqulelo lobuninzi. Nangona ubomi bukaNd: YVO4 imalunga namaxesha ama-2.7 amafutshane kunalawo ka-Nd: YAG, ukusebenza ngokuthambeka kwayo kusengaphakama kakhulu kuyilo olufanelekileyo lomngxunya we-laser, ngenxa yokusebenza kwayo kakuhle kwempompo.
