Cr^（4＋）：YAG激光器特性

Performances of a Cr￣(4+) -doped YAG laser

本文系统地介绍了Ｃｒ４＋：ＹＡＡ的晶体结构和光谱特性以及不同运转条件下国外Ｃｒ４＋：ＹＡＧ激光器的特性。着重阐述了受激态吸收对调谐范围和输出特性的限制，以及吸收饱和时的偏振特性及被动调Ｑ性能。

The crystal structure, spectrum properties and laser performances of a Cr4+ -doped YAGare introduced systematically in this Paper. We also expound the limitation in tuning range and lasingproperties by the excited-state absorption, the polarization and the Passive Q-switch behavior by saturation absorption.
