熔核直徑
英文
nugget size-
Earth ' s large size ( about 12, 740 kilometers across ) ensures that this heat is lost relatively slowly, which explains why our planet still has a molten outer core and volcanic eruptions at its surface
地球因為體積巨大（直徑約1萬2740公里） ，使熱能損耗得相當慢，這說明了為什麼地球至今仍有著熔融的外核，而且地表還有火山噴發。The technical breakthroughs in growth of nd : cngg had been made. in particular, continuous laser operation was achieved from nd : cngg pumped by ld. when the crystal wafer was end - pumped by one bar of ld with 807nm wavelength, the cw laser output power of 123. 1 mw was obtained with slope efficiency of 22. 3 %
本論文用自動化熔體提拉技術成功生長出< 111 >方向的直徑25mm以上，長度80mm以上的平界面無核心nd : cngg單晶，確定了晶體結構和物相，測量了晶體的光譜性能，晶體消光比達到34db ，晶體生長技術有新的突破，實現了連續激光運轉，用單支807nm半導體激光二極體端面泵浦該晶體片子，在國內首次獲得123 . 1mw的1 . 062 m連續激光輸出，斜效率達22 . 3 % 。
