摘要：

The signal waveform observed in optoacoustic measurements is complex and highly dependent on sample for open-cavity cells and pulsed optical excitation. A Helmholtz resonator (HR) cell has been employed to reduce this dependence on sample and thus simplify signal processing. The cell background signal is likewise reduced with the HR cell. An optoacoustic (OA) spectrum of holmium oxide powder is presented to demonstrate the utility of this cell with pulsed dye laser excitation for acquistion of high resolution OA spectra of solids.
