Abstract
A single crystal ingot puller includes a crucible for containing a melt. A single crystal ingot is grown from the melt. A laser system selectively transmits a laser beam to the ingot edge. A controller selectively controls power of the laser to heat the ingot edge such that a local temperature of the edge region is increased.
