中文摘要：
该文从理论上分析了不同泵浦波形下的荧光衰减规律,提出了一种在不同泵浦波形下测量荧光寿命的新方法——双脉冲探测法,即利用探测泵浦脉冲与荧光衰减脉冲的方法测量荧光寿命。通过对样品钕玻璃及Cr：ZnSe晶体的荧光寿命测量表明：利用该方法在不同泵浦波形下能够实现可见及近红外到中红外激光介质的荧光寿命测量。因此,利用该测量方法能够方便、有效的避免通过解卷积求样品荧光寿命的繁琐过程,对测量激光介质在不同泵浦波形下的荧光寿命具有参考价值。
英文摘要：
The present paper analyzes the different pump wave theory under the fluorescence decay law,and presents a different pump wave measured fluorescence lifetime of the new method—double-pulse detection method,namely the use of pump pulse and probe pulse for the fluorescence decay methods to measure fluorescence lifetime.By measuring the sample neodymium glass and Cr：ZnSe crystal fluorescence lifetime,results showed that：using this method can be achieved under different pump wave in visible and near-infrared to the mid-infrared laser medium of the fluorescence lifetime measurement.Therefore,using the measurement method can be convenient and effective to avoid seeking samples by deconvolution for fluorescence lifetime with the cumbersome process of measuring laser medium at different pump wave under the fluorescence lifetime with a reference value.
