要是280毫安的电流,这样的激光器,要是红光的基本可以达到这个功率,要是绿色激光,恐怕也就是5-15毫瓦.关键前提你没说清楚什么波长的激光器.哈哈!!!

<p>不太可能是150ｍｗ绿光，150ｍｗ绿光按10％效率逆推，激光管功率应该是1500ｍｗ，这样输入电流最少应该是1500～2000ｍａ，你自己看是这样吗？</p>

foxwin 发表于 2007-6-13 21:25

请问输入电流是不是就是点亮时候测试出来的电流啊?我用万用表测量了一下,电池4V时候点亮测电流为320mA,532绿光,换算一下大概应该是多少mW啊?

顶多顶多就50ｍｗ吧！是否上当了，当时的价格是多少，150ｍｗ的电筒很贵的一般要2000左右吧。50ｍｗ的价格应该是他的1/4-1/3。

<p>估计是上当了.</p><p></p><p></p>
