Electric supply device for one or more metal vapor lasers using an electric power charging circuit with a variable inductor to provide a variable charging gradient

摘要

Electric supply device for at least one metal vapor laser includes a convertor for converting an a.c. voltage into a d.c. voltage of fixed amplitude. Means are provided for supplying a pulse voltage with a maximum amplitude that can be regulated. An electric power charging circuit including a variable inductor is used for regulating the maximum amplitude of the pulse voltage for each laser.
