这里要是有大款可以弄到兰色LD就爽了,不过是鬼子的.

电阻

要是可以买到DL-6146-301型号的LD,用它做50毫瓦的兰色激光器,体积可以和现在的高功率红色的相比,也就是直径在16毫米,长为180毫米左右,我可以设计光学,电路和机械部分,关键就是LD的价格.颜色为蓝色405纳米.[em01]DL-6146-301<BR>BLUE-VIOLET LASER DIODE<BR>Features<BR>&#8226; Short wavelength : 405 nm (Typ.)<BR>&#8226; Light Output: 50mW CW at 100mW (pulse)<BR>&#8226; Low threshold current : Ith = 40mA (Typ.)<BR>&#8226; Package : &oslash;5.6 mm<BR>Absolute Maximum Ratings<BR>Electrical and Optical Characteristics<BR>Tottori SANYO Electric Co., Ltd.

<P>这个东西太贵了。</P>
<P>另外，尽管蓝色比绿色更好看，但光视觉效率低，即同样是50mW，绿色的看起来要亮得多。</P>
