THE 2-MINUTE RULE FOR ER:YB:YAB CRYSTAL

Phosphate glass combines a long lifetime of Er3+ upper laser degree with efficient Electricity transfer between Yb3+ and Er3+ ions and decreased upconversion losses, Hence delivering successful operation in passively Q-switched diode-pumped and flash-lump pumped lasers used in range-finders.Classes on fundamental, intermediate or Innovative subject
