Chloroaluminum phthalocyanine nanoparticles were successfully prepared by laser ablation in liquid, and the photoacoustic signal of the nanoparticles was measured. Chloroaluminum phthalocyanine powders were irradiated with nanosecond-pulsed laser (Nd:YAG, SHG) to prepare nanoparticles. The particle size of prepared nanoparticles decreased with the increase in laser fluence. Absorbance of prepared nanoparticles was increased with the increase in laser fluence. The ratio between two peaks would be changed because of crystal structure change by photothermal laser heating. The production yield from raw material powder to nanoparticle was 92.8% at a laser fluence of 300 mJ/cm2. The nanoparticle-dispersed solution was stable for 80 days. The photoacoustic signal intensity of prepared nanoparticles increased with the increase in laser fluence.
