    • In the video projector of the present invention, a fiber part (3b) of a fiber laser (3) is disposed so as to draw a circulating orbit of more than one circulation along the inner wall of the projector housing (1). Further, an FBG (14) which constitutes the fiber laser (3) is fixed so that its shape is not changed. Furthermore, a pump LD part (3a) of the fiber laser (3) is disposed apart from the SHG element (5). As a result, the video projector can be miniaturized, and thereby the portability and installment of the video projector are facilitated. Further, the output stabilization of the fiber laser can be realized by preventing the shape change of the FBG. Furthermore, by disposing the SHG element apart from the pump LD part which forms a heat source, the temperature change of the SHG element is suppressed and the wavelength conversion efficiency by the SHG element is enhanced.
    • 在本发明的视频投影仪中,设置光纤激光器(3)的光纤部(3b),沿着投影机壳体(1)的内壁拉出多于一个的循环的循环轨道。 此外,构成光纤激光器(3)的FBG(14)被固定成其形状不变化。 此外,光纤激光器(3)的泵LD部(3a)与SHG元件(5)分开设置。 结果,可以使视频投影仪小型化,从而便于投影机的便携性和安装。 此外,光纤激光器的输出稳定性可以通过防止FBG的形状变化来实现。 此外,通过将SHG元件与形成热源的泵LD部分分开,抑制SHG元件的温度变化,并且提高SHG元件的波长转换效率。
