Nd: Crystal YVO4
Nd: YVO4 (I-Neodymium-doped Yttrium Vanadate) ingenye yezinto ezinhle kakhulu ezitholakala kwezentengiso ze-lasode di-pumped solid-state lasers, ikakhulukazi kuma-lasers anamandla aphansi noma aphakathi nendawo. Isibonelo, Nd: YVO4 kungukukhetha okungcono kuneNd: i-YAG yokukhiqiza izinsimbi zamandla aphansi kuzikhombisi ezibambe ngesandla noma amanye ama-laser acwebile. Kulezi zicelo, Nd: YOV4 inezinzuzo ezithile ngaphezulu kwe-Nd: YAG, isb. Ukufakwa okuphezulu kwe-laser irradiation ne-pumped sigaba esikhulu esivulekile.
Nd: YVO4 kungukukhetha okuhle kokukhipha okunamakhaza amaningi ku-1342 nm, njengoba umugqa wokuphuma unamandla kakhulu kunalawo wezinye izindlela zawo. Nd: YVO4 iyakwazi ukusebenza ngamakhristalu athile angafani nopelethi we-NLO ephezulu (i-LBO, i-BBO, i-KTP) ukukhipha amalambu kusuka eduzane kwe-infrared kuya eluhlaza okotshani, okuluhlaza okwesibhakabhaka, noma ngisho ne-UV.
Xhumana nathi ukuthola isixazululo esihle kakhulu sohlelo lwakho lokusebenza lweNd: YVO4 amakristalu.

Izinzuzo zeNd: YVO4 (qhathanisa neNd: YAG)
• Ibhendi ebanzi yokumpompa ebanzi ezungeze ama-808 nm (amahlandla ama-5 lelo leNd: YAG)
• Isigaba esikhulu esinyusayo sokukhuphuka kwesikhutha ngo-1064nm (amahlandla ama-3 we-Nd: YAG)
• Ukulimala komshini we-laser ophansi kanye nokusebenza kahle kwethambeka eliphakeme
• Okuhlukile ku-Nd: YAG, Nd: YVO4 yisikristalu esingaxutshwe nalutho esikhipha umugqa oqondile emgqeni, sigwema ukungasebenzi kahle okubangwa yi-birefringence.
