Ti:Al2O3
Titanium-doped sapphire (Ti3+:Al2O3) crystal is the most widely used tunable laser solid material, with excellent laser characteristics –the wide emission bandwidth (spanning 0.65 ~ 1.2μm) , excellent thermal, optical, physical, chemical and mechanical properties. Ti:Sapphire lasers and based on them laser systems are unsurpassed in its extraordinary breadth of performance and resulting diversity of applications, such as proton therapy, accelerator physics, nuclear physics, infrared spectroscopy, and materials characterization. CCT produces high quality titanium doped sapphire laser crystals by using superior material quality and then applying precision optical manufacturing techniques. The size can be ϕ160mm according to customer requirements.CasCrysTech (CCT) provides high quality Titanium-doped sapphire (Ti3+:Al2O3) crystals upon request from customers.
