Ho, Cr, Tm: YAG - Doped Ndi Chromium, Thulium Ndi Holmium Ions
Mafotokozedwe Akatundu
Ubwino wobadwa nawo wa kristalo ndikuti umagwiritsa ntchito YAG ngati wolandila. Zathupi za YAG, zotentha komanso zowoneka bwino zimadziwika bwino komanso zimamvetsetsedwa ndi wopanga laser aliyense.
Ma diode kapena ma lasers a nyali ndi ma lasers othamanga omwe amatha kutulutsa pakati pa 1350 ndi 1550 nm amagwiritsa ntchito CTH:YAG (Cr, Tm, Ho: YAG). Kutentha kwambiri kwamafuta, kukhazikika kwamphamvu kwamankhwala, kukana kuwala kwa UV, komanso kuwonongeka kwakukulu ndi mawonekedwe a Cr4 +: YAG. American Elements imatsatira miyezo yoyenera yoyesera ya ASTM ndipo imapanga magiredi osiyanasiyana, kuphatikiza Mil Spec (kalasi yankhondo), ACS, Reagent and Technical Grade, Food, Agricultural and Pharmaceutical Grade, Optical Grade, USP ndi EP/BP (European Pharmacopoeia /British Pharmacopoeia), mwa ena. Pali njira zokhazikika komanso zapadera zonyamula katundu. Chiŵerengero cha Reference Calculator chosinthira pakati pa miyeso yambiri yoyezera yomwe ili yofunika imaperekedwanso, pamodzi ndi chidziwitso china chaukadaulo, kafukufuku, ndi chitetezo (MSDS).
Ubwino Wa Ho:Cr:Tm:YAG Crystal
● Kuthamanga kwambiri kotsetsereka
● Amapopedwa ndi nyali yoyaka kapena diode
● Imagwira ntchito bwino m’chipinda chofunda
● Imagwira ntchito m'mafunde otetezedwa ndi maso
