ABSTRACT:
A control circuit for a pulsed gas laser comprises a plurality of sensors 9, 12, a plurality of control members (e.g. 10) and a central control unit 13. Associated sensors and control members, i.e. sensors which measure a parameter variable by the associated control member, are connected jointly to modules 7, 8, 11 and each module comprises at least one microprocessor; the modules are connected by means of optical waveguides 20 in series in a ring to the central control unit 13. The arrangement makes it possible to save complicated electromagnetic shielding, provides easy fault tracing and simple expansion of the control circuit by further modules.
