摘要:
Disclosed herein is a laptop-size high-order harmonic generation apparatus using near field enhancement. The laptop-size high-order harmonic generation apparatus using near field enhancement includes a femtosecond laser generator, light transfer means for transferring light output from the femtosecond laser generator, micro patterns formed of metallic thin films and configured to have nano-sized apertures for generating near field enhancement when the light output from the light transfer means passes through the micro patterns, a gas supply unit for supplying inert gas to the light when the light transferred through the light transfer means passes through the micro patterns, and a vacuum chamber for accommodating the micro patterns and the gas supply unit under a vacuum atmosphere.
