    • A laser annealing apparatus comprises a laser oscillator having a Q switching action, one or a plurality of partially reflective mirrors for split a laser beam emitted from the laser oscillator into a plurality of laser beams, a plurality of optical fibers which respectively transmit the plurality of laser beams split by the partially reflective mirrors, and whose respective emission ends are arranged linearly in one direction, a first optical system for synthesizing and homogenizing the plurality of laser beams emitted from the optical fibers, and a second optical system for focusing the laser beam emitted from the first optical system on the work piece surface as a rectangular laser beam whose beam shape is long in the lateral direction and short in the longitudinal direction. As a result, laser power transmission by means of slender optical fibers is possible even in cases in which a green laser such as the second harmonic of an Nd:YAG laser having a Q switching action or the like is used as a heating light source. Accordingly, a compact laser annealing apparatus that has a high-quality working performance and does not require a laser amplifier or high-frequency generating apparatus can be obtained.
    • 激光退火装置包括具有Q切换动作的激光振荡器,用于将从激光振荡器发射的激光束分成多个激光束的一个或多个部分反射镜,分别透射多个激光振荡器的多个光纤 由部分反射镜分开的激光束,其各个发射端沿一个方向线性布置;第一光学系统,用于合成和均化从光纤发出的多个激光束;以及第二光学系统,用于聚焦激光束 从工件表面上的第一光学系统发射的光束形状在横向方向上长并且在纵向方向上短的矩形激光束。 结果,即使在使用诸如具有Q切换动作的Nd:YAG激光器的二次谐波的绿色激光等作为加热光源的情况下,也可以通过细长的光纤进行激光功率传输。 因此,可以获得具有高质量工作性能并且不需要激光放大器或高频产生装置的紧凑型激光退火装置。

    • Two laser media are disposed at equal intervals between a first flat mirror, which is a resonator mirror comprising a resonator, and a second flat mirror for separating laser light that transmits second-harmonic laser light and reflects fundamental laser light toward a laser light incident plane; and a dielectric multilayer film is formed on the second flat mirror for separating the laser light. A third flat mirror, which is a resonator mirror, is disposed so as to face a direction 90° to the incident direction of the fundamental laser light in the second flat mirror. A first lens, a nonlinear optical crystal for converting fundamental laser light into a second-harmonic laser light, and a second lens are disposed in sequence in a single row at intervals that are equal to the focal distances f of the first and second lenses between the second and third flat mirrors. Space for accommodating a nonlinear optical crystal and a mirror for separating second-harmonic laser light can thereby be secured while maintaining stabilized resonance conditions, and the output of the solid-state laser generator can be increased.
