The VUV emissions (155 Å) of laser produced plasma on massive plane targets with different Z numbers are recorded according three laser wavelengths with a pinhole camera associated with a multilayered mirror. The 2 D dimensions of these VUV images are compared with the sizes of the focal spots through the 1 Kev pinhole image sizes recorded at the same laser intensity (510 14 W/cm 2 , 600 ps). The lateral and axial dimensions of the VUV emissions of Al, Cu, Au plasmas are analyzed and give informations on the radiations‐hydrodynamic behavior of Laser heated plane targets with respect to the wavelength of the incident laser.
