Nd: YVO4 Crystal
Nd: YVO4 (Neodymium-doped Yttrium Vanadate) ndechimwe chezvakanakisa zvekutengesa zvinhu zvinowanikwa diode-pumped solid-state lasers, kunyanya kune lasers ine yakaderera kana yepakati simba density. Semuenzaniso, Nd: YVO4 iri sarudzo iri nani kupfuura Nd: YAG yekugadzira maburi ane-low-magetsi mumawoko akabata-poers kana mamwe macompact lasers. Mumashandisirwo aya, Nd: YOV4 ine zvimwe zvakanakira pamusoro peNd: YAG, semuenzaniso, yakakura kutora pumped laser kudiridza uye yakakurudzirwa yakasimudzwa muchikamu chikamu.
Nd: YVO4 sarudzo yakanaka yekubuditsa zvakanyanya polarized kuburitsa pa1342 nm, semutsetse weinopinda wakasimba kupfuura iwo ayo mamwe maitiro. Nd: YVO4 inokwanisa kushanda nezvimwe zvisina marara makristuru ane yakakwira NLO coefficient (LBO, BBO, KTP) kugadzira mwenje kubva padhuze nepazasi kusvika kune yakasvibirira, bhuruu, kana kunyange UV.
Bata isu kune mhinduro yakanakisa yako kushandisa Nd: YVO4 makristasi.

Zvakanakira Nd: YVO4 (zvichienzaniswa naNd: YAG)
• Yakajeka kupomba bandwidth yakatenderedza 808 nm (ka5 times iyo yeNd: YAG)
• Huru yakakurudzira kumuka-chikamu chegumi pa1064nm (3 times that of Nd: YAG)
• Lower laser kukuvadza chikumbaridzo uye yakakwirira yekutsetseka kushanda
• Yakasiyana neNd: YAG, Nd: YVO4 is uniaxial krisimasi inopa mutserendende polarized emission, kudzivisa redundant thermally indened birefringence.
