摘要：

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 wasused for recording the fine structure of bands in the region between 610-680 nm in powdered microcrystallinesamples of H02O3and Nd2Ü3. Analysis of high resolution photoacoustic spectra obtained new information onthe Stark components of the ground and excited states of Ho3+and Nd3+in the oxide matrix. © 1990 Optical Society of America.
