| Outline of Final Research Achievements |
Many-body chemical reaction processes induced by intense laser fields are studied by using laser filament formed by femtosecond laser pulses focused by a long focusing length lens. Intense laser pulse (~40 fs, ~1mJ/pulse) were focussed to a gas-cell containing ethylene gas (~1 atm) to form a laser filament. The produced materials were analyzed by using TEM, EELS and XPS etc to show that the main products are hydrogenated amorphous carbons. It was found that the sp2/sp3 carbon ratio and the size of the nano-particles varies sensitively depending on the wavelength and intensity of the laser fields.
