Detailed Selling Lead Description:
Ti:Sapphire (Al2O3:Ti3+)- titanium-doped sapphire crystals combine supreme physical and optical properties with broadest lasing range. Its indefinitely long stability and useful lifetime added to the lasing over entire band of 660-1050 nm challenge "dirty" dyes in variety of applications. Medical laser systems, lidars, laser spectroscopy, direct femtosecond pulse generation by Kerr-type mode-locking - there are few of existing and potential applications.
The absorption band of Ti:Sapphire, centered at 490 nm, makes it suitable for the pump source for a variety of lasers - argon ion, frequency doubled Nd:YAG and YLF, copper vapour lasers. Due to its 3.2 μs fluorescence lifetime, Ti:Sapphire crystals can be effectively pumped by short pulse flashlamps in powerful laser systems.
Red Optronics supplies a wide variety of finished laser rods and slabs. Our standard Ti:Sapphire production follows:
