# Attributes

High quality laser crystals begin with our near perfect crystalline structure and the correct 3+ valence electron state.

Each HEM Ti:Sapphire laser rod guarantees the foundation for your laser platforms’ high power levels and excellent beam profiles.

Through rigorous examination processes and state-of-the-art equipment, our crystals are tested for absorption values, homogeneity, light scatter, FOM, flatness, and transmitted wave fronts.
