Abstract

The optical absorption coefficient of Ti:Al₂O₃ samples at 490 nm for the π polarization (E∥ĉ) is found to be proportional to the concentration of Ti³⁺ ions, as determined by measurement of the paramagnetic moment as a function of temperature and magnetic field. The experimental data yield the value σ=(9.3±1.0)×10⁻²⁰ cm² for the absorption cross section of Ti³⁺, the active ion in the tunable Ti:Al₂O₃ laser, at the peak of the laser pump band.
