(PhysOrg.com) -- While compact fluorescent lights (CFLs) are currently the primary alternative to incandescent light bulbs, a company from Seattle predicts that its own novel light bulbs will eventually replace CFLs and LEDs. ...
Unlike fictional laser swords, real laser beams do not interact with each other when they cross—unless the beams meet within a suitable material allowing for nonlinear light-matter interaction. In such a case, wave mixing ...
