LITTLE KNOWN FACTS ABOUT ER:YB:YAB CRYSTAL.

Phosphate glass combines a long life time of Er3+ higher laser degree with productive Strength transfer in between Yb3+ and Er3+ ions and decreased upconversion losses, Therefore 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 �
