Check out my homepage for further experiments using laser. There are several easy to do examples to split the beam, modulate on of the two and then recombine them to produce low frequency beats. These beats should be able to induce currents into the body to transmit sound or steer muscles if used with high power lasers. You dont even need a laser, this can be done with ordinary light and heat radiation as well. The double slit experiment mostly is done with an ordinary light source.

For anyone who is wondering what this fresnel lens came from:
Just do an image search on google using the words "tv screen enlarger".

"flea market" is direct translation of the expression for "2nd hand goods bazaar" in Turkish(bit pazarı, flea market). really surprising.
