利用电子偏折术（electron deflectometry）研究了强度为1 × 1016 W/cm ~ 2的飞秒激光脉冲在固体靶表面附近产生的电场随时间的演化规律。我们发现，电场的数量级为108 V/m的沿着的目标表面产生和衰减内400 fs。这项研究的结果表明，在飞秒时域测量超快现象的电子偏转的潜力。
The temporal evolution of the electric field generated near the surface of a solid target by a femtosecond laser pulse with intensity of 1 × 1016 W/cm2 has been investigated by electron deflectometry; in this technique, ultrashort electron pulses generated by intense femtosecond laser pulses are used as probes. We found that electric field of the order of 108 V/m along the target surface was generated and decayed within 400 fs. The results of this study demonstrate the potential of electron deflectometry for measuring ultrafast phenomena in the femtosecond time domain.
