Abstract
A method of making a cutting element for use on an earth-boring tool may include forming the cutting element including a cutting table formed from a superabrasive polycrystalline material. The method may further include polishing a cutting surface of the cutting table by pulsing a laser onto the cutting surface of the cutting table. The cutting element may include a superabrasive polycrystalline cutting table including a cutting surface substantially free of micro-anomalies in the superabrasive material.
