According to the formula of time relationship of laser induced voltage signal in high temperature superconductor (HTSC) and giant magnetoresistive (CMR) film, the equation of optimal thickness of thin film required to generate maximum laser induced voltage is further derived. The results show that the induced voltage is not Is simply proportional to the reciprocal of the thickness but has an optimum thickness.The equation gives the main factors that influence the device response design and discusses the film parameters that determine the optimum thickness and compares them with the experimental results
