摘　　要：钛宝石（Ｔｉ∶Ａｌ２Ｏ３）晶体是一种优良的可调谐激光晶体，具有广泛的用途．作者用焰熔法在还原焰条件下生长钛宝石晶体（氢∶氧约为３．０～３．６∶１）时，通过采用不同的掺杂方式及粉料焙烧工艺，并使用合适的拉晶速率及合理调整下粉量等措施后，较好地解决了焰熔法生长钛宝石晶体时价态容易变化的问题，保证了钛宝石晶体生长价态的确定性，得到了晶形良好的钛宝石晶体．The Ti∶sapphire single crystal is a kind of excellent laser crystal that has tunning character and has been widely used.Using the Verneuil Technique,the authors have grown large single crystal of Ti∶sapphire (under the condition of H 2∶O 2=3.0～3.6∶1).By use of the different doping means and powder falling rate.The authors tackle the problem of Ti 3+ existence and find that the powder production technique has the effect on the droped ion valance of Ti in crystal growth.
