Results of PE-SiO2 target. (a) the CO/CH4, CO2/CH4, CO2/CO, and C2H2/CH4 ratio of the produced gas as functions of O/C ratio of targets. Results of 0.5, 1 and 2 mm laser beam diameter (laser intensity is fixed at 1×109 W/cm2) are shown. Solid line shows the result of nominal case; laser beam diameter 1 mm and laser intensity 1×109 W/cm2. (b) The CO/CH4, CO2/CH4, CO2/CO, and C2H2/CH4 ratio of the produced gas as functions of laser beam diameter. Results of O/C = 10, 4 and 2 are shown.
