Abstract
The pulsed laser control system comprises a plurality of controllers (2) through (6) for controlling devices (21) through (30) constituting the pulsed laser apparatus (1); parallel communication lines (P1) to (P4) for parallel connection of the plurality of controllers (2) through (6); an Ethernet (S) for serial connection of the plurality of controllers (2) through (6); parallel communication line (PP) for parallel connection between the external apparatus (10) and the main controller (2); and an Ethernet (SS) for serial connection between the external apparatus (10) and the main controller (2); wherein the parallel communication lines (P1) to (P4) 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.
