Ti：sapphire再生放大器输出的主要参数为脉冲能量、宽度和信噪比．另外还有一个重要参数为输出脉冲能量的稳定性．目前，国际上Ti:sapphire再生放大器的输出稳定性可控制在5％（rms）以内．影响再生放大器输出稳定性的因素主要有泵浦脉冲能量起伏和角漂移．对于工作在1．056μ
Ti: sapphire regenerative amplifier output of the main parameters of pulse energy, width and signal to noise ratio. In addition there is an important parameter for the stability of the output pulse energy. At present, the output stability of the Ti: sapphire regenerative amplifier can be controlled within 5% (rms) in the world. The main factors that affect the output stability of regenerative amplifier are pump pulse energy fluctuation and angular drift. For working at 1.056μ
