The group of Stephen Wilson from University of California, Santa Barbara, recently demonstrated floating zone crystal growth at 700 bar gas pressure. In a recent Review of Scientific Instruments publication the authors present a second-generation design of the high-pressure laser floating zone furnace, “Laser Optical Kristallmacher II” (LOKII), featuring two ScIDre pulling drives which were specifically developed and build for the furnace. Innovative laser beam path redirection dramatically improves the imaging quality and pyrometric temperature measurements compared to the first generation. The presented growth of several representative oxides demonstrates the ability of a high-pressure growth environment to tune the chemical potential and mitigate the material volatility.
