Product Description

blue colored sapphire lens for watch case glass surface/ color sapphire glass optical lens / customized color/ yellow pink orange purple red color sapphire 


 Sapphire crystals are active media for highly efficient tunable solid-state lasers. They demonstrate good operation in the pulsed-periodic, quasi-CW and CW modes of operation. Ti:Sapphire is a 4-level, Vibronic laser with fluorescence lifetime of 3.6 µm. The peak of the absorption band is 490 nm which makes it an excellent material for pumping with a variety of sources operating in the green-argon ion, copper vapour, frequency-doubled Nd:YAG, and dye lasers are routinely used. Crystals have also been flashlight pumped by lamps designed to allow short fluorescence lifetime. These factors and broad tunability make it an excellent replacement for several common dye lasing materials. The crystals are grown using the Czochralsky and the Ciropolous techniques.
