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。
The effective pumping energy provided by the xenon lamp determines the number of inverted particles in the neodymium glass. According to the requirements of xenon lamp power supply, a numerical model of xenon lamp discharge circuit and xenon lamp radiation was established. The numerical simulation results are compared with the experimental results. A method of solving the optimal pumping parameters by simulating annealing algorithm is proposed and the working conditions of xenon lamp under different circuit parameters are simulated. Two more useful evaluation parameters are defined: effective radiation efficiency and effective output spectral efficiency, which are used to screen the best pump energy and light power. The calculation results show that the parameters of the xenon lamp and the working voltage can be used to quickly optimize the parameters of the capacitor and inductor in the discharge circuit through the simulated annealing algorithm so as to avoid the share of effective energy in the pumping band Blue shift and reduce the spectrum, while ensuring the life of xenon lamp.
