Technology and characterization of Nd:YAG ceramics

The Nd:YAG ceramics of 1% and 2% Nd dopant were produced by a solid-state reaction of high-purity (4N) nanometric oxides powders, i.e., Al2O3, Y2O3, and Nd2O3. Mean grain sizes of about 20 mu m and grain boundaries less than 5 nm of Nd:YAG ceramic samples were evaluated in SEM and TEM measurements....

Zusammenfassung:	The Nd:YAG ceramics of 1% and 2% Nd dopant were produced by a solid-state reaction of high-purity (4N) nanometric oxides powders, i.e., Al2O3, Y2O3, and Nd2O3. Mean grain sizes of about 20 mu m and grain boundaries less than 5 nm of Nd:YAG ceramic samples were evaluated in SEM and TEM measurements. Two types of active elements: rods and slabs were fabricated and characterized in several diode pumping schemes. In the best case, 3.7 W of output power, M2 < 1.4 were demonstrated for uncoated ceramics 2% Nd:YAG rod of phi 4 x 3 mm size in preliminary experiments. In case of Nd:YAG ceramic slab above 12 W was demonstrated.
