Abstract

By means of time-resolved site-selective spectroscopy the formation of new Tm³⁺ optical centers with modified local environment and presumably tetragonal local symmetry in CaF₂ hot-formed laser quality ceramics is observed. The spectroscopic properties of these new Tm³⁺ optical centers are investigated and shown to differ strongly from that for regular tetragonal optical centers.
