We report on a single-state measurement of electrical conductivity of warm dense gold in the solid to plasma transition regime. This is achieved using the idealized slab plasma approach of isochoric heating of ultrathin samples by a femtosecond laser, coupled with femtosecond probe measurements of reflectivity and transmission. The experiment also reveals the time scale associated with the disassembly of laser heated solid.
我们报告了在固体到等离子体转变区域对温稠密金的电导率进行的单态测量。这是通过飞秒激光对超薄样品进行等容加热的理想化平板等离子体方法实现的，并结合了飞秒探针的反射率和透射率测量。该实验还揭示了与激光加热固体解体相关的时间尺度。
