5 SIMPLE TECHNIQUES FOR ER:YB:YAB CRYSTAL

Phosphate glass combines an extended lifetime of Er3+ upper laser stage with productive energy transfer concerning Yb3+ and Er3+ ions and reduced upconversion losses, Consequently giving successful operation in passively Q-switched diode-pumped and flash-lump pumped lasers used in vary-finders.language �?中国 韩国 韩国 韩国 韩国 韩国
