Cool laser weapon, but why...............

[Destroyer]

In 1979 I was a machinery broker buying some equipment from a company called Holophane in NJ that make nothing but special lights. (They made the night lights for the space launches) I watched them shoot a laser into another laser, and then that beam into a third laser, and then that beam into yet another laser... and then that beam destroyed a cinder block in about 1/5 of one second.. just a bang and the block had this huge hole in it. Then the company moved literally overnight to a new location and I never heard from them again... how very strange...
