    • The focal point of a working laser beam is made to follow precisely the laser-beam irradiated face of an object to be worked. A cutting-scheduled line (5) is irradiated along itself with a measuring laser beam. An astigmatism is added to the reflected light reflected on such a surface (3) of the working object (1) as is irradiated with the measuring laser beam. A displacement sensor signal is detected according to the focused image of the reflected light having the astigmatism added. A displacement sensor signal is made to have the feedback reference value according to the light quantity of the reflected light, so that the focal point ofthe working laser beam is adjusted to a predetermined position with respect to the surface (3). Even if an area having an extremely low reflectivity of the measuring laser beam is partially present so that the light quantity of the reflected light of the measuring laser beam drops, the focal point of the working laser beam drops can follow the surface (3) of the working object (1) reliably and precisely.
    • 使工作激光束的焦点精确跟随待加工物体的激光束照射面。 切割预定线(5)自身用测量激光束照射。 在被照射测量激光束的工作物体(1)的这种表面(3)上反射的反射光加上像散。 根据添加了散光的反射光的聚焦图像来检测位移传感器信号。 使位移传感器信号根据反射光的光量具有反馈参考值,使得工作激光束的焦点相对于表面(3)调节到预定位置。 即使测量激光束的反射率极低的区域部分地存在,使得测量激光束的反射光的光量下降,工作激光束的焦点落下也可以遵循 工作对象(1)可靠而精确。

    • A laser irradiation device for crystallizing amorphous silicon is provided to progress a stabilized crystallization process by lessening average density difference due to laser beam irradiated afterwards, although laser beam with large energy density is irradiated. A laser irradiation device(101) for crystallizing amorphous silicon comprises a laser beam generation device(110), a first homogenizer(115), a second homogenizer(120), a short axis light collecting lens(125), an objective lens(130), a slit(135) and structures. The laser beam generation device radiates laser beam. The first homogenizer is located in a front surface of the laser beam generation device. The second homogenizer is spaced from the first homogenizer, and opposite to the laser beam generation device each other. The short axis light collecting lens is spaced from the second homogenizer. The objective lens is spaced from the short axis light collecting lens. The structures have bar shape and block a part of the laser beam.
