high quality Sapphire Lens

Product Description

Sapphire becomes a promising material for tunable lasers if doped with elements possessing wide absorption bands and wide emission regions. The most interesting among such elements are Ti 3+ , Cu 2+ , V 3+ , Ni 2+ , Co 2+ , Co 3+ , and Mn 2+ . Concerning
three-dimensional elements, the widest luminescence spectrum is characteristic of titanium.

Titanium-doped sapphire (Ti:sapphire, ticor, Ti:S) is one of the key active media of tunable lasers. It has been used since 1982, when the generation of this crystal was reported for the first time .  



Although there are lots substrates which are regarded as potential materials to replace sapphire substrate, it is still dominated in the substrates (for GaN LED growth) market, because of its reasonable price and relatively low mismatch. Zhongju is capable of processing substrates according to customer needs. Currently, our sapphire substrate productions ranges from 2 to 12 inches with high quality and accurate orientation.
