Erbium Glass (Er,Yb:Glass)
Er,Yb:Glass/Er, Yb, Cr: Glass product, also known as erbium glass (er glass), is a kind of laser glass with good comprehensive performance.
Er3+, Yb3+ co-doped phosphate glass (Er, Yb: phosphate glass) is a well-known and commonly used active medium. It emits laser microns in the “eye safe” spectral range of 1.5 – 1.6um.
1540 nm laser is just located at the position of human eye safety and optical fiber communication window. So it leads to laser generation and signal amplification.
1540 nm laser has been widely used in range finder, radar, target recognition, and other fields.
Phosphate glass combines the long-lived (~8 ms) laser level on 4I13/2 Er3+ with the low-lived (2-3 ms) 2F5/2 excited state of 4I11/2 Er3+ level resonant with Yb3+.
The fast nonradiative multiphonon relaxation from 4I11/2 to 4I13/2 is due to the interaction between Yb3+ and Er3+ ions excited at 2F5/2 and 4I11/2 levels, respectively. That dramatically reduces the reverse energy transfer and conversion losses.
Er3+/Yb3+ co-doped phosphate glass is an LD pumped 1540 nm eye-safe radiation source. It can emit eye safe 1540 nm laser radiation directly used in laser rangefinders and telecommunications.
Er, Yb glass laser with 1540 nm wavelength radiation output does not need to add additional components.
Er3+/Yb3+ co-doped phosphate glass laser is an eye-safe wavelength laser. It has attracted much attention because of its compactness and low cost.
Eat14: Yb3+, Er3+ co-doped phosphate glass, suitable for high repetition rate (1-6Hz) laser diode pumped 1535 nm. High Yb3+ doping can be achieved in this Eat14 glass.
