Questions Arising When One Laser Beam Crosses Another

Carl R. Littmann
Year: 2009 Pages: 6
Many youngsters have likely tried to ?cut' or deflect one laser (pointer) beam with another; and noted that they could not detect any effect whatsoever. But what if that type of experiment was performed with very hi-tech, powerful, and sensitive equipment? Like is done with the high energy ?particle smashers ? except trying to get photon to side-swipe photon, instead of proton to hit proton? We discuss some very important implications depending on whether a ?photon-against-photon' deflection can be obtained. (If any reader already knows of any ?down-to-earth' experiment settling the issue; please provide answer with reference, and spare readers most of my article, below.)
