| description | To properly grasp that optical characteristics of a laser beam are varied.SOLUTION: A beam diameter of a laser beam LB reflected by a first beam splitter 23 is detected by a first image detection part 25. A beam diameter of the laser beam LB reflected by a second beam splitter 24 is detected by a second image detection part 26. In a calculation part 31, a variation amount of a focal position of the laser beam LB and a variation amount of power of the laser beam LB are calculated on the basis of detection results of the first image detection part 25 and the second image detection part 26. In a determination part 32, the state of an optical system is determined on the basis of the calculation results by the calculation part 31.SELECTED DRAWING: Figure 2
【課題】レーザ光の光特性が変動したことを適切に把握できるようにする。【解決手段】第１ビームスプリッタ２３で反射されたレーザ光ＬＢのビーム径が第１画像検出部２５で検出される。第２ビームスプリッタ２４で反射されたレーザ光ＬＢのビーム径が第２画像検出部２６で検出される。演算部３１では、第１画像検出部２５及び第２画像検出部２６の検出結果に基づいて、レーザ光ＬＢの焦点位置の変動量と、レーザ光ＬＢのパワーの変動量とが演算される。判定部３２では、演算部３１の演算結果に基づいて、光学系の状態が判定される。【選択図】図２ |
