Erbium Laser glass Erbium and ytterbium co-doped phosphate glass has a broad application because of the excellent properties. Mostly,Website:http://www.meta-laser.com, it is the best glass material for 1535nm laser due to its eye-safe wavelength of 1535 nm and high transmission through atmosphere. Its also suitable for medical applications where the need for eye protection may be difficult to manage or diminish or hinder essential visual observation.We could provide four kinds of Erbium-doped glasses for different use, WM4, Cr14, EAT14 and CrE5Features:WM4: Erbium phosphate glass for ion-exchange purpose;Cr14: Erbium phosphate glass for xenon lamp pumping laser device and laser range-finderEAT14: Yb3+, Er3+ co-doped phosphate glass, which is applicable in high repetition rate (1-6Hz) laser diode pumped 1535nm laser. High Yb3+ doping can be realized to this EAT14 glass.CrE5: CrE 5 is for large energy output application. The glass rod of CrE5 can work safely at 1Hz repetition after surface strengthing treatment at over 10J output level.
