共掺Nd^（3＋）离子改善了Cr：ZnWO_4的激光效率

Codoped Nd￣(3+)Ion Improved Lasing Efficiency of Cr: ZnWO4 Crystal

共接Ｎｄ３＋离子改善了Ｃｒ：ＺｎＷＯ４单晶质量，提高了激光效率。室温下用红宝石激光泵浦，在φ６×１９ｍｍ的晶棒中，获得０．９５μｍ的激光脉冲，最大输出能量达１．６２ｍＪ，泵浦斜率效率为０．７９％。

Codoped Nd3+ ion improved the quality of Cr:ZnWO4 single crystal and raisedits lasing efficiency.Laser pulse at wavelength 0.95 μm was generated with a 6 mmdiameter,19 mm long rod,which was pumped with a ruby laser The maximum outputenergy is 1.62 mJ and the slop efficiency is 0.79 %.
