A SIMPLE KEY FOR ER:YB:YAB CRYSTAL UNVEILED

Phosphate glass brings together a long lifetime of Er3+ upper laser level with efficient energy transfer between Yb3+ and Er3+ ions and reduced upconversion losses, thus furnishing 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 We
