The Heat Exchange Method (HEM) has been developed to grow the highest quality sapphire crystals available worldwide.

Ti-sapphire HEM high performance laser rods are manufactured to meet the most demanding customer requirements. Careful selection and quality control at all stages, from crystal growth to
final fabrication, allow production of the highest performance Ti:sapphire laser rods available.

HEM sapphire components are used in a wide of applications in commercial, industrial, scientific, and military markets. Sapphire is the leading transparent engineering material for demanding window, substrate and military mid-wave infrared (MWIR) window and dome applications.
