Pfupi Tsananguro:

Nd: YAG (Neodimium Doped Yttrium Aluminium Garnet) yave uye ichipfuurira kuva iyo inonyanya kushandiswa laser kristallita kune yakasimba-nyika lasers. Hupenyu hwakanaka fluorescence (yakapetwa kupfuura iyo yaNd: YVO4) uye inodzika mafuta, pamwe nemagariro akasimba, ita Nd: YAG kurira kwakanyatsokodzera kumusoro-simba rinoramba richingove mafungu, yakakwirira-simba Q-yakachinja uye kamwechete maitiro mashandiro.

Nd: YAG (Neodimium Doped Yttrium Aluminium Garnet) yave uye ichipfuurira kuva iyo inonyanya kushandiswa laser kristallita kune yakasimba-nyika lasers. Hupenyu hwakajeka fluorescence (yakapetwa kaviri kupfuura iyo yeNd: YVO4) uye inopisa conductor, pamwe nemhando yakasimba, ita Nd: YAG kurira kwakakodzera kwazvo-yakasimba-simba kuenderera mafungu, yakakwirira-simba Q-yakachinja uye kamwechete maitiro mashandiro.

WISOPTIC inopa Nd: YAG tsvimbo iine zvinotevera maitiro: akasiyana doping mazinga, yakakwirira Optical homogeneity, yakakwirira kugadzirwa kurongeka, chaiyo barrel kugomera uye wedge angle, akasiyana magumo kucheka, akasiyana dielectric kuvhara, yakakura kukuvadza chikumbaridzo.

Bata isu kune mhinduro yakanakisa yako kushandisa Nd: YAG makristasi.

WISOPTIC Kugona - Nd: YAG

• Kusarudzwa kwakasiyana-siyana kweNd-doping ratio (0,1% ~ 1.3at%)

• Kusarudzwa kwakasiyana-siyana kwetsvimbo kana slabs (flat, wedged, Brewster, yakagadziriswa, nezvimwewo)

• High Optical homogeneity

• Yakakwira yekugadzirisa kurongeka

• Yakakwirira mhando kubatira, yakakura kukuvadza chikumbaridzo

• Yakanyanya kukwikwidzana mutengo, kukurumidza kutumira
