LITTLE KNOWN FACTS ABOUT ER:YB:YAB CRYSTAL.

Phosphate glass combines a protracted life time of Er3+ higher laser level with effective Strength transfer concerning Yb3+ and Er3+ ions and reduced upconversion losses, Therefore giving successful operation in passively Q-switched diode-pumped and flash-lump pumped lasers used in range-finders.Classes on basic, intermediate or Superior matters ï¿
