  density dip
    The results obtained by computation are in agreement not only with the laser-target experiments using Nd-glass laser, but also with that using CO2 laser. In addition, calculations show naturally the density dip which has been observed in experiments.
    我们的计算结果不仅与Nd玻璃激光打靶实验相符,也与CO_2激光打靶实验相一致,而且还能自然得到临界面附近的密度凹陷

    From two dimensional steady state plasma fluid equations, assuming a balance of radial electron thermal pressure and radial pondermotive force in the cyliudrical symmetrio distribution of electron density in laser irradiated region, the analytical results have been deduced of radial electron density dip structure in the laser field region and the axial electron density profile steepening near the critical density due to the pondermotive force. The analytical results are consistent with the experimental results measured by a 266nm UV optical pbobe.
    从等离子体二维流体方程出发,假定在柱对称电子密度分布的等离子体中,在激光辐射场的区域内,径向电子热压与径向有质动力在稳态情况下平衡,推导出了由有质动力引起的临界密度面附近轴向电子密度轮廓陡变和有场区径向电子密度凹陷结构的解析结果,此结果与266.0nm紫外激光探针所测到的实验结果相符合。

    Using interferometric diagnostics by visible probing beam, we have studied the electron density profiles in coronal plasmas of solid targets irradiatied by Nd glass laser at an intensity of 1014 W/cm2. We have observed not only the phenomena such as density steepening and hollowing due to light pressure, but also different characters of density hollowing in various configuration targets.

  density dip
In the long wavelength, non-dispersive limit, a density dip - which is initially present as a small disturbance - grows rapidly and remains localized in the plasma.
      
It has been shown that the presence of second component of ions modifies the nature of dust-acoustic solitary structures and may allow rarefactive dust-acoustic solitary waves (solitary waves with density dip) to exist in such a dusty plasma system.
      
As a pump pulse driving a plasma wave traversed the sharp density dip, injection of electrons was observed.
      
Hence the detection of such a deeply depleted density dip is clear proof of the passage of an intense laser pulse.

In this paper, a coupled system of Langmuir solitary wave and light solitary wave is obtained. These coupled solitary waves appear to have some new features compared with the single Langmuir solitary wave or the single light solitary wave.

本文得到了高低频、双流体、无外磁场,初始密度为均匀时,等离子体动力学方程组的一个双向一维平面高频横波(光波)和纵波(Langmuir波)耦合的孤立波系,它的离子密度凹陷的深度和宽度与实验结果基本一致。这种耦合的孤立波与单独的光孤立波或Langmuir孤立波比较,表现出若干新的性质。

The effects of self-generated magnetic field on the density profile modification in laserplasma interactions are studied by calculating the field structure, assuming that plane electromagnetic waves propagate into an one-dimensional inhomogeneous magnetized plasma. The results obtained by computation are in agreement not only with the laser-target experiments using Nd-glass laser, but also with that using CO2 laser. In addition, calculations show naturally the density dip which has been observed in experiments....
