Product Description

Nd:YVO4 inogona kugadzira ine simba uye yakagadzikana IR, yakasvibira, yebhuruu lasers ine dhizaini yeNd:YVO4 uye frequency yakapetwa kaviri makristasi.Kune maapplication ayo akawedzera compact dhizaini uye imwechete-longitudinal-modhi yekubuda inodiwa, Nd: YVO4 inoratidza ayo chaiwo mabhenefiti pamusoro pemamwe anowanzo shandiswa laser makristasi.

Zvakanakira Nd:YVO4

● Low lasing chikumbaridzo uye yakakwirira slope kushanda zvakanaka
● Huru inokurudzirwa kuburitsa kuyambuka-chikamu pakureba kwewavelength
● Kunyura kwepamusoro pamusoro pekupomba kwakafara kwewavelength bandwidth
● Optically uniaxial uye hombe birefringence inobudisa polarized laser
● Kudzikira kutsamira pakupomba wavelength uye inowanzobuda mumodhi imwe chete
