Line emission profiles of doubly-ionized aluminium doublets at 360 and 570 nm are measured in a laser-produced plasma (n e = 0.2-1.6 10 19 cm -3 , kT = 3-8 eV) to study line broadening in dense and cold plasmas. The density and temperature of the plasma are measured independent of spectral measurements using interferometry, absorption and absolute emission diagnostics...
