WebJun 1, 1999 · We define harmonics as voltages or currents at frequencies that are a multiple of the fundamental frequency. In most systems, the fundamental frequency is 60 Hz. Therefore, harmonic order is 120 Hz, 180 Hz, 240 Hz and so on. (For European countries with 50 Hz systems, the harmonic order is 100 Hz, 150 Hz, 200 Hz, etc.) WebAug 26, 2002 · We demonstrated the energy scaling of high-order harmonics using a self-guided beam under the phase-matched condition. By adjusting the argon gas density and pump laser focusing condition, a total output harmonic energy as high as 0.7 μ J was obtained in the spectral region of 34.8 to 25.8 nm (the corresponding order of the 23rd to …

Time-frequency representations of high order harmonics

WebHigh harmonic generation (HHG) can be induced by focusing an intense laser onto either gas atoms [ 1–5 ], solids [ 6–11 ], or liquids [ 12, 13 ], as sketched in Figure 1. By invoking … WebHigh-order harmonics generated by intense laser pulses in gases have been investigated over the last three decades as a means for providing new extreme ultraviolet and soft x-ray light sources. They are also responsible for the emergence of attosecond science [1, 2]. When harmonics are generated in iowa straight wall cartridge deer
