Abstract:
A method for producing a crystalline material in a crucible in a crystal growth apparatus is disclosed. The method comprises, in part, the step of determining the amount of solidified material present in a partially solidified melt produced during the growth phase using at least one laser positioned at a height above the crucible. A crystal growth apparatus comprising the laser is also disclosed.
