Erbium oxide

1. Erbium oxide doped laser crystal and its output 1730nm laser and 1550nm laser are safe for human eyes, good for atmospheric transmission, strong for battlefield smoke penetration, good confidentiality, not easy to be explored by the enemy, large contrast for illuminating military targets, and have been made into a portable laser rangefinder safe for human eyes in military.
3. Er3 + in the glass can be made into rare earth glass laser material, which is the solid laser material with the largest output pulse energy and the highest output power.
4. Er3 + can also be used as the activation ion of laser materials on rare earth.
5. Nano erbium oxide can also be used in the decolorization and coloring of glasses and crystal glasses.
