Titanium-doped sapphire crystal (abbrev. for Ti:Sapphire, chemical formular- Ti3+:Al2O3) combine supreme physical and optical properties with broadest lasing range (660nm-1050nm), which sever as the most widely used gain medium for the wavelength tunable laser and for the femtosecond pulse generation and amplification systems. Ti:Sapphire laser has been widely employed in the numerous applications such as telecommunications, spectroscopic research, industrial process, ultrafast processing monitoring, production of X-rays etc..
We can supply optical polished laser rods and slabs that meet your requiremenst. The main specifications of our Ti:Sapphire crystal are listed in the table.
