Nd: YAG - Yakanakisa Solid Laser Material
Product Description
Nd: YAG ichiri yakasimba-nyika laser zvinhu ine yakanakisa yakazara kuita.Nd: YAG lasers anopombwa optically achishandisa flashtube kana laser diodes.
Aya ndiwo mamwe emhando dzakajairika dzelaser, uye anoshandiswa kune akawanda akasiyana maapplication.Nd: YAG lasers anowanzo buritsa mwenje ine wavelength ye1064nm, mune infrared.Nd: YAG lasers inoshanda mune ese ari maviri pulsed uye anoenderera modhi.Pulsed Nd: YAG lasers anowanzo shandiswa mune inodaidzwa kuti Q-switching mode: Optical switch inoiswa mu laser cavity yakamirira kuwanda kwevanhu inversion mune neodymium ions isati yavhurwa.
Ipapo iyo mwenje wave inogona kumhanya nepakati, ichibvisa iyo inonakidza laser yepakati pahuwandu hwehuwandu inversion.Mune iyi Q-switched modhi, masimba ekubuda e250 megawatts uye pulse durations ye10 kusvika 25 nanoseconds awanikwa.[4]Iyo yakakwirira-yakasimba pulses inogona kuve yakanyatso kupetwa kaviri kugadzira laser mwenje pa532 nm, kana yakakwirira harmonics pa355, 266 uye 213 nm.
Iyo Nd: YAG laser tsvimbo inogadzirwa nekambani yedu ine hunhu hwekuwana yakakwira, yakaderera laser chikumbaridzo, yakanaka yekupisa conductivity uye kupisa kwemafuta.Inokodzera zvakasiyana-siyana zvekushanda modes (inopfuurira, pulse, Q-switch uye mode kukiya).
Inowanzoshandiswa mupedyo-kure-infrared solid-state lasers, frequency kaviri uye frequency tripling application, Inoshandiswa zvakanyanya mukutsvagisa kwesainzi, kurapwa, indasitiri uye mamwe minda.
