Nd: YVO4 Crystals

Nd:YVO4 shine mafi inganci Laser rundunar crystal don diode famfo a cikin na yanzu kasuwanci Laser lu'ulu'u, musamman, ga low zuwa tsakiyar ikon yawa.Wannan ya fi dacewa don ɗaukarsa da fasalin fitar da shi wanda ya wuce Nd: YAG.Pumped by Laser diodes, Nd:YVO4 crystal an haɗa shi tare da manyan lu'ulu'u masu inganci na NLO (LBO, BBO, ko KTP) don mitar-canza fitarwa daga infrared na kusa zuwa kore, shuɗi, ko ma UV.Wannan hadewa don gina duk m jihar Laser ne manufa Laser kayan aiki da za su iya rufe mafi tartsatsi aikace-aikace na Laser, ciki har da machining, kayan aiki, spectroscopy, wafer dubawa, haske nuni, likita bincike, Laser bugu, da kuma bayanai ajiya, da dai sauransu It. An nuna cewa Nd: YVO4 tushen diode famfo m jihar Laser suna hanzari shagaltar da kasuwanni bisa ga al'ada mamaye ruwa-sanyi ion Laser da fitila-pumped Laser, musamman a lokacin da m zane da guda-tsayi-mode fitarwa ake bukata.
Nd:Fa'idodin YVO4 akan Nd:YAG:
• Kamar yadda girman kusan sau biyar ya fi girma sha mai inganci a kan fa'ida mai fa'ida mai fa'ida a kusa da 808 nm (saboda haka, dogara ga tsawon tsayin famfo yana da ƙasa da ƙaƙƙarfan hali ga fitowar yanayin guda ɗaya);
• Girma mai girma kamar sau uku mafi girma tsokar hayaki giciye a lasing wavelength na 1064nm;
• Ƙarƙashin lasing ƙofa da ingantaccen gangara;
• A matsayin kristal uniaxial tare da babban birefringence, fitar da shi kawai ne kawai ta hanyar layi.
Abubuwan Laser na Nd:YVO4:
• Daya mafi kyawun hali na Nd:YVO4 shine, idan aka kwatanta da Nd:YAG, yawan adadin sha na sau 5 mafi girma a cikin mafi girman bandwidth mai faɗi a kusa da tsayin famfo mafi tsayi na 808nm, wanda kawai yayi daidai da ma'auni na diodes mai ƙarfi mai ƙarfi a halin yanzu.Wannan yana nufin ƙaramin kristal wanda za'a iya amfani dashi don Laser, wanda zai haifar da ƙarin tsarin tsarin laser.Don ƙarfin fitarwa da aka ba, wannan kuma yana nufin ƙaramin ƙarfin wutar lantarki wanda laser diode ke aiki, don haka ƙara tsawon rayuwar diode laser mai tsada.Babban fa'idar ɗaukar bandwidth na Nd:YVO4 wanda zai iya kaiwa sau 2.4 zuwa 6.3 fiye da na Nd:YAG.Bayan ingantaccen yin famfo, yana kuma nufin babban kewayon zaɓi na ƙayyadaddun diode.Wannan zai zama taimako ga masu yin tsarin laser don ƙarin juriya don zaɓin ƙananan farashi.
• Nd:YVO4 crystal yana da mafi girma ƙara kuzari giciye sassan, duka a 1064nm da 1342nm.Lokacin da a-axis ya yanke Nd: YVO4 crystal lasing a 1064m, yana da kusan sau 4 sama da na Nd: YAG, yayin da a 1340nm ɓangaren giciye ya fi girma sau 18, wanda ke kaiwa ga aikin CW gaba daya ya wuce Nd: YAG. ku 1320nm.Waɗannan suna sa Nd:YVO4 Laser ya zama mai sauƙi don kula da hayaƙin layi ɗaya mai ƙarfi a tsawon zango biyu.
Wani muhimmin hali na Nd:YVO4 lasers shine, saboda uniaxial ne maimakon babban ma'auni na cubic kamar Nd: YAG, kawai yana fitar da laser mai layi mai layi, don haka yana guje wa tasirin birefringent da ba a so akan jujjuyawar mita.Duk da cewa rayuwar Nd:YVO4 ta yi kusan sau 2.7 ya fi na Nd:YAG, ingancinsa na gangara na iya kasancewa har yanzu yana da tsayi sosai don ingantaccen zane na rami na Laser, saboda yawan ingancin famfun sa.
