Titanium doped Sapphire (Ti3+:Al2O3 or Ti:Sapphire) is the most widely used crystal for wavelengths tunable lasers. It combines the excellent thermal, physical and optical properties of
Sapphire with the broadest tunable range of any known material. It can be lased over the entire band from 660 to 1100 nm. Frequency doubling provides tunability over the blue-green region of the visible spectrum.
Ti: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.

FAQ:
Q1. Is your company a factory or trade company?
We have a factory and we also can do export ourself.We are the Sapphire Window manufactuer.
Q2.Is you company only work with sapphire business?
no,at present our company work with sapphire business and other semiconductor materials
as like sic, LT,GaAs. but We process sapphire components and Ruby components as the center
of gravity at present.
Q3. Could you supply sample?
Yes,we can supply sapphire sample according to customer's requirement.
Q4. Do you have any stock of sapphire window?
We process sapphire window according to customer requirement.So we have few sapphire
window in stock.
Q5. Where is your company located?
Our company located in shanghai,China. factory is in Wuxi city.
Q6. How long will take to get the products?
Generally it will take 2~4 weeks to process.It is depend on the quantity and the size
of the sapphire products.
