The cool lighting effects seen here were created by using a handheld flash and colored gel filters, not PhotoShop. The camera was set up on a tripod and the shutter was kept open for a couple of minutes. Mother Nature (it was still daylight outside) provided the "laser beams" here.

A number of weapons contractors have had facilities at this site including Lockheed-Martin, Hughes Aircraft and General Dynamics. The engines for the Atlas missile and Centaur rocket stage were tested at this site.
