Nd YAG
Yakagadzirwa mumakore makumi matanhatu ezana ramakore rapfuura, Nd: YAG yanga iri uye inoramba iri yakanyanya kushandiswa laser crystal kune yakasimba-nyika crystal zvinhu.Yayo laser paramita ibvumirano yakanaka pakati pesimba uye kushaya simba kwemakwikwi ayo.Nd: YAG makristasi anoshandiswa mumhando dzese dzeakasimba-state lasers.Kuenzaniswa nemamwe makristasi e-laser, hupenyu hwayo hwefluorescence hwakapetwa kaviri kupfuura Nd:YVO4, uye kupisa kwekushisa kuri nani zvakare.
Features uye Applications
★ Kurasika kwakaderera pa1064 nm, High Optical Quality, Yakanaka Mechanical uye Thermal Properties
★ Kuwana Kwepamusoro, Kuderera Kwepasi, Kubudirira Kwepamusoro
★ Nekuda kwe cubic symmetry uye mhando yepamusoro, Nd: YAG iri nyore kushanda neTEM00 modhi.
★ Gadzira yebhuruu laser ine frequency-yakapetwa kaviri ye946nm
★ Iva Q-inoshandurwa neCr: YAG zvakananga
★ Ishandiswe mune yakanyanya simba re laser kusvika kuKW level
