A laser machining system contains a laser processing unit, a controller for controlling the laser processing unit in accordance with a laser machining per gram, and a new start - preparatory unit for carrying out a preparation of the control for a resumption of the program execution according to the ejection. The new start - preparatory unit has an operating state - judging unit, which determines whether an operating state of the machining unit in the case of suspension of the program execution in the course of a laser machining, and a restart condition a specification unit, which is a restart condition of the machining unit specified when the program execution, namely of predetermined conditions on the basis of a judging result. The operating state - determining unit determines that the operating state in the course of the laser machining, when a predetermined operation command for the working of the workpiece is output by the control, or if a predetermined external information for the machining of the workpiece in the control system for the time of the ejection of the program execution is entered.
