    I remember seeing this ad in the back of PopSci. Never ordered one, so I never knew how powerful a laser you could build from these plans. Anyone out there try to build a “laser pistol” from Roy Davis Labs?

    I had a friend that purchased this set plan, the laser used a ruby rod and large flash bulb it was pumped from one end and the beam cam out the other. Power was very poor due to the poor concentration of the light from the flash bulb. A laser pointer has more power. It wouldn’t pop a balloon.
