Er: YAG Makristasi
Er: YAG imhando yeakanakisa 2.94 um laser crystal, inoshandiswa zvakanyanya mulaser medical system uye mamwe minda.Er: YAG crystal laser ndiyo inonyanya kukosha zvinhu zve3nm laser, uye mutsetse unoshanda zvakanyanya, unogona kushanda pakamuri tembiricha laser, laser wavelength iri mukati mechikamu chebhendi rekuchengetedza ziso remunhu, nezvimwe. 2.94 mm Er: YAG laser ine. yakashandiswa zvakanyanya mukuvhiya mumunda wekurapa, runako rweganda, kurapwa kwemazino.
Zvakanakira Er:YAG Makristasi:
• High kutsetseka kushanda zvakanaka
• Shanda zvakanaka pakamuri tembiricha
• Shanda munzvimbo isina njodzi yewavelength
