摘要： A cylindrical lens (4) diverges a laser beam (L1) in the Y-axis direction (i.e., within the YZ plane) but neither diverges nor converges it in the X-axis direction (i.e., within the ZX plane). An objective lens (5) converges the laser beam (L1) emitted from the cylindrical lens (4) into a point P1 in the Y-axis direction and into a point P2 in the X-axis direction. As a consequence, the cross section of the laser beam (L1) becomes elongated forms extending in the X- and Y-axis directions at the points P1, P2, respectively. Therefore, when the points P1, P2 are located on the outside and inside of the work (S), respectively, an elongated working area extending in the Y-axis direction can be formed in a portion where the point P2 is positioned within the work (S).
摘要翻译：柱面透镜（4）在Y轴方向（即，在YZ平面内）分散激光束（L1），但是在X轴方向（即，ZX平面内）中也不会发散或会聚。物镜（5）将从柱面透镜（4）射出的激光束（L1）向Y轴方向的点P1会聚，并将X轴方向的点P2会聚。因此，激光束（L1）的横截面分别成为在点P1，P2处沿X轴方向和Y轴方向延伸的细长形状。因此，当点P1，P2分别位于工件（S）的外侧和内部时，可以在点P2位于工件（S）内的部分中形成沿Y轴方向延伸的细长工作区域（S）。

摘要： A cylindrical lens (4) diverges a laser beam (L1) in the Y-axis direction (i.e., within the YZ plane) but neither diverges nor converges it in the X-axis direction (i.e., within the ZX plane). An objective lens (5) converges the laser beam (L1) emitted from the cylindrical lens (4) into a point P1 in the Y-axis direction and into a point P2 in the X-axis direction. A pair of knife edges (13) adjust the divergence angle (θ) of the laser beam (L1) incident on the objective lens (5) in the Y-axis direction. As a consequence, the cross section of the laser beam (L1) becomes an elongated form extending in the Y-axis direction at the point P2, while the maximum length in the Y-axis direction is regulated. Therefore, locating the point P2 on the front face of a work (S) can form an elongated working area extending in the Y-axis direction by a desirable length on the front face of the work (S).
