摘　　要：在H .Lengfellner等人推导的激光感生电压公式以及笔者推导出的YBa2 Cu3O7-δ薄膜激光感生电压信号随时间变化公式的基础上 ,进一步导出产生最大激光感生电压所需的薄膜最佳厚度的方程式 .该方程给出了影响器件响应设计的主要因素 .Based on the equation of laser induced voltage deduced by H. Lengfellner, and the equation of time dependence of laser induced voltage deduced by the authors, the equation of optimum thickness for producing largest laser induced voltage is deduced, which provides the main factors of affecting the design for fast time response device. And the theoretical calculated result of the equation of optimum thickness for producing largest laser induced voltage is coincident with experimental ones quite well.
