Abstract
A laser heated pedestal growth system includes two lasers having output beams that are combined with a beam combiner to produce a single beam. A growth chamber that includes a final focusing mirror for receiving and focusing the single beam of the lasers onto a tip of a feed material to create a molten zone in a focal region. A feed transport mechanism is adapted for transporting a feed material through the growth chamber and into the molten zone. An opposing seed transport mechanism is adapted for withdrawing a seed material from the growth chamber. An imaging system is adapted for capturing an image of the molten zone within the growth chamber. A controller in communication with the feed transport mechanism, the seed transport mechanism, one of the two lasers, and the imagining system is adapted to control and stabilize a fiber growth process by controlling the feed transport mechanism, the seed transport mechanism, and the power of the combined laser beam.
