时间分辨，亚微米密度尺度的皮秒激光产生的等离子体的长度测量使用共振吸收轮廓光谱。从皮秒激光脉冲在等离子体中吸收的角度和偏振依赖性推断出临界密度处的密度标度长度。研究了皮秒激光照射Au靶产生的等离子体的早期膨胀，测量的标度长度在1000\char21{}~ 5000 A {}范围内.
Time-resolved, submicron density scale lengths in picosecond laser-produced plasmas are measured using resonance absorption profile spectroscopy. The density scale length at critical density is inferred from the angle and polarization dependence of the absorption of a picosecond laser pulse in a performed plasma. The early expansion of picosecond laser-produced plasmas produced from an Au target is studied, with measured scale lengths in the range of \ensuremath{\sim}1000\char21{}5000 A\r{}.
