摘要
本文介绍了中频感应加热提拉法生长Ｎｄ：ＹＡＧ晶体所需要的设备、仪器与工艺条件。通过对生长装置的温度分布的研究，确定了生长Φ４０～４５ｍｍＮｄ：ＹＡＧ晶体的温场。在此温场条件下，较好地生长出Φ４０～４５ｍｍＮｄ：ＹＡＧ晶体，晶体的成炉率为８６．５％，加工成的激光棒成品率为８５％，其中Φ３～６．５ｍｍ系列的优级品率２１％；Φ７～１２ｍｍ系列的优级品率１５％。在我国率先建立了Φ３～１２ｍｍＮｄ：ＹＡＧ激光棒系列，该系列产品在许多军工和民用项目上得到了良好的应用。
In the paper the growth equipmen, instruments and technical conditions for growing greater size Nd:YAG crystal by mid-frequency inductively heating and pulling method are introduced.The temperature field for growing Φ40～45mm Nd:YAG crystal was found by studying temperature distribution of crystal growth units. On the condition of this temperature field , the Nd:YAG crystals with 40-45mm in diameter were grown successfully,and radio of crystal growth success is 86%. The ratio of successfully fabricated laser rods is 85%, including 21% high-quality reds with size of 3～6.5mm in diameter,15% high-quality rods with size of 7～12mm in diameter,and serial products of laser rods with size of Φ3～12 mm were supplyed firstly on the domestic market.
