摘要
氙灯提供的有效抽运能量决定了钕玻璃中反转粒子的数目。针对氙灯供能的要求,建立了氙灯放电回路与氙灯辐射数值模型。将数值模拟结果与实验结果进行了比对,提出了利用模拟退火算法求解最优抽运状态的电路参数的方法,并模拟计算不同电路参数下氙灯的工作状态。定义了两个更实用的评价参数:有效辐射效率和有效输出光谱效率,用于筛选最佳的抽运能量和进灯功率。计算结果表明,在氙灯参数与工作电压一定的条件下,通过利用模拟退火算法可以快速优化放电回路中的电容、电感参数,以选择最佳的进灯能量,避免抽运带内有效能量份额因光谱蓝移而降低,同时可保证氙灯的使用寿命。
Abstract
For the number of inversion is decided by the effective pumping power provided by xenon flashlamp, the xenon discharge circuit and flashlamp radiation numerical model are built. With the use of the numerical method and the model above, the xenon flashlamp characters under different circuit parameters are calculated and compared to the experimental results. Two more practical concepts effective radiation efficiency and effective spectral efficiency are defined, to select optimal pumping energy and power entering xenon lamp. The results show that simulated annealing algorithm can be used to choose best capacitor and inductance rapidly , when the coefficients of xenon lamp and operating voltage remain constant. And the optimal power entering the lamp is also picked in this way. This method not only avoids the lowering of valuable energy proportion in the pumping area due to the violet-shift in spectrum, but also guarantees the life of the xenon lamp.
