Nice yellow laser

Here s a quick overview of my new Spartan Yellow laser from DragonLasers This is my first 589nm yellow laser, and I m really happy with it. Yellow lasers are pricy, but have a unique beam that all laser hobbyists seem to love. In this video, the laser runs in the 40mW50mW range, but can run as high as 85mW when a little bit cooler. The driver has linear regulation, and sucks down 2. 25A at 3. 7V, so this definitely is not an efficient laser Beam divergence is about 1. 05mRad. All in all I am happy with
