PROBLEM TO BE SOLVED: To provide a program capable of preventing the flow of a high transient current from flowing, even if the scan rate of a galvano-mirror is high, and a laser processing apparatus.SOLUTION: A predetermined drawing to be laser-processed is decomposed of a plurality of straight lines. In accordance with the decision that the one decomposed straight line has a length L or higher, there are created first coordinate data and second coordinate data. The first coordinate data are either the coordinate data of an internal point indicating the end point of a segment which is set at a scanning velocity later than an ordinary one of a galvano-scanner 18 positioned at a first interval d1 from the starting point of a straight line, or the coordinate data of an inner point expressing the end point of a segment set at a scan rate slower than the ordinary scanning rate of the galvano-scanner 18 on a straight line. The second coordinate data are the coordinate data of one or more inner points expressing the end point of a segment set at the ordinary scan rate of the galvano-scanner 18 on the straight line.SELECTED DRAWING: Figure 17 【課題】ガルバノミラーの走査速度が速くても、大きな過渡電流が流れることを防ぐことができるプログラム及びレーザ加工装置を提供すること。【解決手段】レーザ加工対象の所定の図形が複数の直線に分解される。その分解された一つの直線が直線の長さＬ以上であると判断した事に応じて、第１座標データと第２座標データが生成される。第１座標データは、直線の始点から第１間隔ｄ１に位置し且つ直線上でのガルバノスキャナ１８の通常の走査速度よりも遅い走査速度に設定される線分の端点を表す内点の座標データ、又は直線の終点から第２間隔ｄ２に位置し且つ直線上でのガルバノスキャナ１８の通常の走査速度よりも遅い走査速度に設定される線分の端点を表す内点の座標データである。第２座標データは、直線上でのガルバノスキャナ１８の通常の走査速度に設定される線分の端点を表す一又は複数の内点の座標データである。【選択図】図１７
