Abstract

Threshold effects occurring in fragmentation of stones using a 504 nm microsecond pulsed dye laser were investigated in relation to the optical properties of the stone. Threshold measurements performed on 13 stones appeared to be roughly proportional to the diameter of the fiber. The optical penetration depth, measured opto acoustically yielded values between 0.7 and 3.2 micrometers . The threshold varied exponentially with the optical penetration depth.
