SPS-processed 1.5 at% Nd:YAG (a) in-line transmittance spectrum, sample appearance insert, (b) SEM image of fracture surface microstructure, close-up on pore in top insert and (c) porosity distribution obtained by CLSM in reflection mode. The same follows for the HPSPS-processed 1.5 at% Nd:YAG sample (d–f) with insert in (e) being a TEM image.
