Cr Yb Erglass 1970°C Melting Point 800 W/M Thermal Shock Resistance Parameter

Er,Cr,Yb:Glass

Erbium Glass doped with Er3+, Yb3+ and Cr3+, Erbium doped glass laser provides a useful coherent source in the spectral range near 1.5 m, which is relatively safe for the human eye and is convenient in many applications, such as lidar and range measurements, fiber-optic communication, and laser surgery. In spite of the considerable progress in the development of InGaAs laser diode pump sources, Xe flashlamp will continue to be used as pump sources of Er:glass lasers because of their high reliability and low cost, and also the simplicity of design of such systems. Since about half the flashlamp radiation energy is emitted in the visible and near infrared (IR) ranges, a second sensitizer Cr3+ is introduced into Yb-Er laser glasses to utilize this energy.
