For the present study, 1.1‐at.%‐neodymium‐doped yttrium aluminum garnet (YAG) ceramics with a controlled pore volume (150‐930 vol. ppm) were fabricated via a solid‐state reaction method using high‐purity powders. The scattering coefficients of neodymium‐doped YAG (Nd:YAG) ceramics, obtained from Fresnel's equation, increased simply as the pore volume increased. The effective scattering coefficient and the laser‐oscillation performance of Nd:YAG ceramics with a pore volume of ∼150 vol. ppm were almost equivalent to those of a 0.9‐at.%‐Nd:YAG single crystal fabricated via the Czochralski method.
