A piezoelectric detection system for recording photoacoustic (PA) spectra of materials in the condensed phase was designed and fabricated. A Nd--YAG laser pumped tunable dye laser with a bandwidth of 0.05 nm was used for recording the fine structure of bands in the region between 610--680 nm in powdered microcrystalline samples of Ho{sub 2}O{sub 3} and Nd{sub 2}O{sub 3}. Analysis of high resolution photoacoustic spectra obtained new information on the Stark components of the ground and excited states of Ho{sup 3+} and Nd{sup 3+} in the oxide matrix.
