Zusammenfassung:	To provide a laser machining device more appropriately controlling optical output of an emission head when the operation time of the laser machining device is elongated.SOLUTION: A laser machining device makes a control part execute an output correcting operation repeating plural times a detection value acquisition step for acquiring a detection value of a power monitor and a correction step for correcting a current command value CV to a current command value when a linear function value specified on the basis of a threshold current of a plurality of laser diodes, a command value at the time of executing the detection value acquisition step and a detection value acquired by the detection value acquisition step becomes a predetermined target value.SELECTED DRAWING: Figure 7 【課題】レーザ加工装置の運転時間が長くなった場合に、出射ヘッドの光出力をより適切に制御できるようにする。【解決手段】レーザ加工装置の制御部に、パワーモニタの検出値を取得する検出値取得ステップと、複数のレーザダイオードの閾値電流、検出値取得ステップの実行時における指令値、及び検出値取得ステップにより取得された検出値に基づいて特定される一次関数の値が所定の目標値となる場合の電流指令値に、電流指令値ＣＶを補正する補正ステップとを複数回繰り返す出力補正動作を実行させる。【選択図】図７
