Titanium Doped Sapphire - Ti:Sapphire
Al2O3:Ti3+ – titanium-doped sapphire crystals combine supreme physical and optical properties with broadest lasing range.
It’s 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 variety of laser pump sources – argon ion, frequency doubled Nd:YAG and YLF, copper vapour lasers. Because of 3.2 µs fluorescence lifetime Ti:Sapphire crystals can be effectively pumped by short pulse flashlamps in powerful laser systems.
Czochralski grown Ti:Sapphire crystals of highest optical quality, figure of merit and different doping levels are routinely available from EKSMA OPTICS.
