I recently observed a natural ruby laser in a lake in about 8 inches of water while fishing. It appeared to be generating a beam about .05" in diameter on ambient light. Possibly, the light was entering from the sides because it was early in the morning. The narrow beam of light was not spreading in the water and it was almost vertical with the water. It looked like a laser pointer. I noticed a bright red spot in the water and examined it closer. I tried to pick it up (in hind site I think I was successful). It appeared to be a plain brown piece of sand. Unfortunatly, I through it back in thinking I missed it.
