Product Overview

Description

Chinese factory hot sale optics erbium glass rod

Erbium and ytterbium co-doped phosphate glass has a broad application because of the excellent properties. Mostly, it is the best glass material for 1535nm laser due to its eye-safe wavelength of 1535 nm and high transmission through atmosphere. It’s also suitable for medical applications where the need for eye protection may be difficult tomanage or diminish or hinder essential visual observation. We can also produce erbium laser glass with various ions doping according to your requirement. WM4: Erbium phosphate glass for ion-exchange purpose; Cr14: Erbium phosphate glass for xenon lamp pumping laser device and laser range-finder. EAT14: Yb³⁺ , Er³⁺ co-doped phosphate glass. CrE5 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.

Features
