Spectra emitted by laser produced plasmas of light elements when observed with spatial resolution show the H-Iike Lyman lines strongly broadened and asymmetrically self-absorbed especially near the target. The case of Lα, Lβ and Lγ lines of B V is analysed in detail. Temperature, density and plasma dimensions have been spectroscopically determined. A model for the emitting plasma, that takes into account Stark and Doppler broadening, motion Doppler shift and optical opacity, has been devised that succesfully explains the observed profiles. Diagnostic possibilities are outlined.
