The optical conductivity of a dense femtosecond laser-heated aluminum plasma heated to 0.1-1.5 eV was measured using frequency-domain interferometry with chirped pulses, permitting simultaneous observation of optical probe reflectivity and probe pulse phase shift. Coupled with published models of bound-electron contributions to the conductivity, these two independent experimental data yielded a direct measurement of both real and imaginary components of the plasma conductivity.
利用啁啾脉冲频域干涉测量法，测量了加热至0.1 - 1.5电子伏特的高密度飞秒激光加热铝等离子体的光导率，从而能够同时观测光探针反射率和探针脉冲相移。结合已发表的关于束缚电子对电导率贡献的模型，这两个独立的实验数据直接测量了等离子体电导率的实部和虚部。
