| Abstract: | 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. |
