6 Inch Sapphire Ingot

2 inch 4 inch 6 inch Sapphire ingot

Historically, the crystals meant for laser elements were obtained by the Verneuil method. In the present day, the crystals employed for this purpose are grown from the melt by the Czochralski, Kyropoulos, and HEM methods and possess the high-est optical homogeneity . The growth media used in the crystal growth...

120kg Clear sapphire ingot

A zone scheme of an interactive system of traps has been proposed in the crystal, which includes a TL-active trap, a luminescence center, and a deep trap. One of the mechanisms responsible for the dose-characteristic linearity is the interactive coupling of the dosimetric and deep traps. Practical recommendations are...
