We explored the impact of infrared light pulses on the field emission performances of carbon nanotubes (CNTs). Carbon nanotubes, which were multiwalled CNTs with the length of 6–10µm and diameter of 20–40nm, synthesized by chemical vapor deposition (CVD) to serve as field emission cathodes. The power of infrared light pulse was 1W laser pulse with the wavelength of 1.06µm. The field emission performances...
