The Stark broadening parameters are an important characteristic of plasma radiation and are widely used for plasma diagnostics, even without LTE. At present, a large theoretical base of Stark line parameters has been collected, but sometimes has low trust factor and the lack of experimental data is still a problem. The work is devoted to the experimental determination of the widths and shifts of lines caused by the quadratic Stark effect for the spectral series 3p-nd/ns Na I and 4p-nd/ns K I.
