摘　　要：本文研究了钠分子高位三重态荧光寿命的测量方法。利用倍频晶体模拟等频双光子激发过程和对荧光衰变曲线求卷积的数值计算方法。有效地消除了测量仪器响应函数的影响,测量了Na_2高位三重态2~3∏_g→a^3∑_u^+的荧光寿命。This paper studies the measuring method of fluorescence lifetime for the high-lying triplet state of Na2. The response function influence on the measuring apparatus has been eliminated effectively by simulating the equifrequent two-photon excitation process with the frequency doubler and numerically calculating the convolution of the fluorescence decay curve. Then, the fluorescence lifetime of the high-lying triplet state 23Πg-a3 Σu+ in Na2 has been measured.
