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。
This article describes the equipment, instruments and process conditions required for growing Nd: YAG crystals by intermediate frequency induction heating and pulling. By studying the temperature distribution of the growth device, the temperature field of Φ40 ~ 45mmNd: YAG crystal was determined. Under this temperature field condition, the Φ40 ~ 45mmNd: YAG crystal grows well, the rate of crystallization of the crystal is 86.5%, the finished laser rod yield is 85%, of which Φ3 ~ 6.5mm Grade rate of 21%; Φ7 ~ 12mm series of excellent grade rate of 15%. In our country the first to establish Φ3 ~ 12mmNd: YAG laser rod series, the series of products in many military and civilian projects have been a good application.
