Abstract:

This work reports the fabrication of composite transparent ceramics consisting of Nd:YAG as the central part and Cr4+:YAG as the edge cladding. The central part of ceramics was shaped into 14-mm-diameter disk or 11-mm-side square and an outer diameter of the edge cladding was 18 mm or 23 mm, respectively. The central part of ceramics exhibited an optical transmittance of ~ 84% at a wavelength of 1.06 µm. The concentration of Cr4+ in Cr4+:YAG ceramics with three different compositions was evaluated using measured transmission spectra and known absorption cross sections. Taking into account the infeasibility condition for self-excitation, the optimal composition of edge cladding was estimated to be 2.5 mol.% Cr + 0.5 mol.% Ca + 97 мол.% YAG.
