曾几何时,589 - 594 nm波段黄色激光几乎是富哥玩物,几毫瓦功率也要小几千,而如今不要998,只要198![](http://tb2.bdstatic.com/tb/editor/images/face/i_f03.png?t=20140803)

品牌未知,标称波长591nm(我持怀疑态度,感觉可能是593.5),标称光功率<200mW,双7号碱性电池供电,实测可用单10440锂电池+占位筒方式驱动,但是对寿命影响暂时不明确。
7号电池供电时电压3.2V,电流280mA,但是一旦电压降至2.8V附近极有可能导致推不动泵浦LD,此时只会亮起十分微弱的绿光,不会触发正常的黄光。
工作温度区间狭小,预热不足时为微弱绿光,过热时黄光会跳模降功率,比较难绷。但是正常工作区间内光斑为非常完美的TEM00正圆形,还得是DPSS!![](http://tb2.bdstatic.com/tb/editor/images/face/i_f25.png?t=20140803)

实测出光功率(含红外泄露等)峰值在20mW左右(我的功率计不太容易归零,读数24,减去本底4得出),白天很暗,晚上稍显明显,光路比较难以察觉,远距离照射亮度也十分不足
