From the SEM analysis of the cross section of the sample, we could judge the dispersion of phthalocyaine indium in PMMA matrix. A UV_Vis spectrophotometer (UV1240) was used to test the UV_Visible spectrum of sample. The sample showed the typical absorption of Q_region at 620 nm to 730nm wavelength. There was a wide non_resonance area at 480 nm to 570 nm wavelength, and the phenomenon of reverse saturable absorption occurred accordingly. An ns/ps Nd:YAG pulsating laser device was used to test the characteristic reverse saturable absorption of the sample. The limited threshold of the sample reached 68.5 mJ/cm2, its dynamic range was 1.07 and the damage threshold was more than 1200 mJ/cm2.展开更多
