You are going to have a hard time doing this with a laser. You might want to try ultrasound sensors instead.

Sparkfun (www.sparkfun.com) has some easy to use sensors which could easily be interfaced to an arduino.

His very poor "Engrish" (he is in India) is on many electronics chat forums recently. Nobody knows what he is talking about.
He also doesn't know much about electronics.
