Pulsed laser control system

Abstract

The pulsed laser control system comprises a plurality of controllers ( ) through ( ) for controlling devices ( ) through ( ) constituting the pulsed laser apparatus ( ); parallel communication lines (P ) to (P ) for parallel connection of the plurality of controllers ( ) through ( ); an Ethernet (S) for serial connection of the plurality of controllers ( ) through ( ); parallel communication line (PP) for parallel connection between the external apparatus ( ) and the main controller ( ); and an Ethernet (SS) for serial connection between the external apparatus ( ) and the main controller ( ); wherein the parallel communication lines (P ) to (P ) and (PP) transmit signals for which realtime performance is required. With this construction, even if design changes are frequently made to a pulsed laser apparatus, the changes can be made easily and with little expansion space. Moreover, management of the devices constituting the pulsed laser apparatus can be easily performed.
