Abstract:

This work reports the fabrication of composite transparent ceramics consisting of a Nd:YAG central part and a Cr4+:YAG 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 similar to 84\% at the wavelength of 1.06 mu m. The concentration of Cr4+ in Cr4+:YAG ceramics with three different compositions was evaluated using measured transmission spectra and reported absorption cross sections. Taking into account the infeasibility condition for self-excitation, the optimal composition of edge cladding was estimated to be 2.5 at\% Cr, 0.25 at\% Ca:YAG.
