Highly frequency Ti+ doped (Titanium doped)/ Cr+ doped sapphire single crstal used in laser / optical / sapphire laser crystals,ruby glass ball/ ruby sapphire lens
Ruby is one of hardest known material with consistent quality available on a commercially economical scale.
With a hardness of 2300 HV it is much more harder then most of the known hard materials like ceramics, etc.
Ruby raw material is grown in a factory by Melting ultra pure Al2O3 at temperature higher then 2000 deg. Celcius to create a single crystal. This hard material has the ability to be polished to a very good surface finish.
Sapphire and Ruby Ball Lenses. Sapphire and Ruby ball lenses are bothmade from Al 2 0 3. Ruby or Ruby-Doped sapphire owes its red color totraces of chromium oxide (chromium content for ruby balls is typically>0.5%). While their physical and chemical properties are basically the same, their optical properties are somewhat different.
Ruby is a three-level laser material. It is generally made of a high-performance aluminum oxide crystal with 0.03 - 0.4% Cr3+, which is made into artificial ruby, which is much better than ordinary natural ruby. performance. Common ruby rods range in size from 0.5 cm to 2 cm in diameter and 4 cm to 16 cm in length. It may look like a very light pink glass rod or a very deep reddish brown, depending on the concentration of Cr in the stick. It will be very special to get in with a green laser pointer.
Product Name: Ruby (Cr: Al2O3) crystal substrate
Product Description:Al2O3 single crystal (Sapphire, also known as white stones, sapphire) has good thermal properties, excellent electrical characteristics and dielectric properties, and anti-chemical corrosion, it is high temperature, thermal conductivity, high hardness, infrared transparent, chemically stable good.

Testing of Single Crystal Material
After crystal growth,we will test each single crystal,testing after passing will be next step
Each crystal materila will need to be cut into the crystal, material selection, processing molding.
Divided into: grinding and polishing. Grinding: Before polishing, grinding needs to stick into a crystal rods, grinding on the grinding disc. Polishing: After grinding, the crystals mounted on the end face polishing machine for polishing. Each base processing usually takes 6 hours.
For the finished product, Finished product testing:We need to check the following index: surface finish, flatness, parallelism. perpendicularity.
Coating is coated with layers ranging from film in the end face of the crystal to achieve transmition and reflection. (Coating or not according to the actual situation)
Finished product storage
The finished product will be packed in a warehouse and send you by express as soon as possible.
