My New Yellow Laser!!
发布人
https://www.youtube.com/watch?v=-fqayC1RbjY 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 40mW-50mW 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 my purchase. DragonLasers does NOT guarantee any sort of minimum power output rating with this laser, so it is a risk to buy. It seems most people are happy with their purchases on the forums though!
