    Zida zoyambira

    Nd: YVO4 ndiye kristalo woyang'anira makina osanja kwambiri opangira ma diode pakati pamakristasi amakono a laser, makamaka, pakuchepa kwamagetsi mpaka pakati. Izi makamaka chifukwa cha mayamwidwe ndi zotulutsa zake zopitilira Nd: YAG. Wopopedwa ndi ma diode a laser, Nd: YVO4 kristalo yaphatikizidwa ndi makhiristo okwera a NLO (LBO, BBO, kapena KTP) kuti amasinthidwe pafupipafupi kuchokera kuzowunikira mpaka kubiriwiri, buluu, kapena UV. Kuphatikiza kumeneku kuti apange ma lasers olimba ndi chida choyenera cha laser chomwe chitha kufalitsa ntchito za lasers, kuphatikiza makina, kukonza zinthu, kuwonera makanema, kuwunika kofufutira, zowunikira, kuwunika kwachipatala, kusindikiza kwa laser, ndi kusungira deta, ndi zina zambiri. zawonetsedwa kuti Nd: YVO4 yochokera pa diode yolimba ya lasers ikukhala mwachangu m'misika yomwe nthawi zambiri imakhala yolamulidwa ndi ma lasers amadzi ozizira ndi ma lasers opopera nyali, makamaka pakapangidwe kakang'ono ndi zotulukapo zazitali zazitali.
    Nd: Ubwino wa YVO4 kuposa Nd: YAG:
    • Kutalika kwakanthawi kokwanira kasanu kuposa kupendekera kwapafupifupi 808 nm (chifukwa chake, kudalira kwa kutalika kwa kutalika kwa mapampu kumakhala kotsika kwambiri komanso chizolowezi chazomwe zimatulutsa);
    • Kukula kwakukulu kwakanthawi kochulukirapo katatu kupititsa patsogolo kotulutsa kutalika kwa 1064nm;
    • Malo ocheperako komanso otsetsereka kwambiri;
    • Monga galasi losasunthika lokhala ndi birefringence yayikulu, umunawo umakhala wowerengeka kwambiri. 
    Laser Katundu wa Nd: YVO4:
    • Khalidwe limodzi lokongola kwambiri la Nd: YVO4 ndi, poyerekeza ndi Nd: YAG, mayendedwe ake opitilira kasanu mozama palimodzi pamayikidwe oyenda bwino ozungulira 808nm pachimake pampope wavelength, omwe amangofanana ndi mulingo wa ma diode a mphamvu yayikulu a laser omwe akupezeka pano. Izi zikutanthauza kristalo yaying'ono yomwe ingagwiritsidwe ntchito ndi laser, ndikupita ku makina ophatikizika a laser. Mphamvu yopatsidwa, izi zimatanthauzanso mphamvu yamagetsi yotsika pomwe laser diode imagwiranso ntchito, motero kupititsa patsogolo nthawi yapa laser diode yokwera mtengo. Kukula kwa bandiwifi kwakukulu kwa Nd: YVO4 komwe kumatha kufikira 2.4 mpaka 6.3 nthawi ya Nd: YAG. Kuphatikiza pakupopera koyenera, kumatanthauzanso kusankha kosiyanasiyana kwamitundu yosiyanasiyana. Izi zikhala zothandiza kwa opanga makina a laser kuti athe kulolerana pazosankha zotsika mtengo.
    • Nd: YVO4 kristalo ili ndi magawo akuluakulu opatsirana, onse pa 1064nm ndi 1342nm. Pamene olamulira adula Nd: YVO4 kristalo yonyamula pa 1064m, imakhala pafupifupi nthawi 4 kuposa ya Nd: YAG, pomwe ku 1340nm gawo lolimbikitsidwa limakhala lokulirapo kakhumi ndi kasanu ndi kamodzi, zomwe zimapangitsa kuti ntchito ya CW isathe kwathunthu Nd: YAG pa 1320nm. Izi zimapangitsa Nd: YVO4 laser kukhala yosavuta kukhalabe ndi chingwe chimodzi cholimba pama wavelengths awiri.
    • Khalidwe lina lofunika la Nd: YVO4 lasers ndi, chifukwa ndilosakanikirana m'malo moyerekeza kwambiri kiyubiki monga Nd: YAG, limangotulutsa laser yolumikizana motere, potero limapewa zovuta zosafunikira pakusintha kwamakanema. Ngakhale moyo wa Nd: YVO4 ndiwofupikitsa nthawi 2.7 poyerekeza ndi wa Nd: YAG, magwiridwe ake otsetsereka akadatha kukhala okwera kwambiri kuti apange laser patsekedwe, chifukwa cha mpope wake wapamwamba kwambiri.
