A5_7 Laser Pool

Thomas Graham, Felix Kaiser, Connor Keany, Rhys Newland, Kishen Pankhania


In this paper we ask the question of how feasible the concept of laser pool would be (using a laser instead of a pool cue). The laser is initially considered to be of comparable diameter to that of the ball, and is compared to a more focused beam. The geometry of the system is considered in detail, calculating how much photon momentum is transferred to the ball. We find the required laser power is approximately 3 × 1023W for the wide laser, and 5 × 1010W for the focused laser.
