Abstract

Tm3+-doped BaCaBO3F crystals have been grown by the Czochralski method. The grown crystals have been inclined to crack along the (001) plane due to the layered structure. Polarization absorption spectra have been recorded at room temperature. The peak absorption cross-sections around 800 nm are 0.84×10-20 cm2 with full width at half maximum (FWHM) of 17.4 nm for π-polarization and 1.18×10-20 cm2 with FWHM of 16.5 nm for σ-polarization, respectively. The Judd-Ofelt theory, extended to anisotropic system, has been applied to evaluate the spectroscopic parameters relevant for laser applications, such as phenomenological intensity parameters, spontaneous transition probabilities, branching ratios and radiative lifetimes..
