High order harmonics
WebApr 14, 2024 · Firstly, it is found that high-order harmonic voltage promotes the partial discharge generation, but DC component suppresses the discharge. Moreover, the charge inside the pressboard is mainly injected in the same polarity and accumulates over time. The space charge density near the electrode increases with the increase of harmonic … WebHis main area of research is the nonlinear optics, particularly high-order harmonics generation of laser radiation in laser-induced plasmas and investigation of the nonlinear optical properties of various materials. He is …

WebHarmonic emissions are generally not in line with the ‘traditional’ emission profile of simple rectifier or inverter circuits. In many cases, the highest emission magnitudes occur at … WebHigh-order harmonics (blue) are generated in an argon gas cell. The IR is filtered out by an IR antireflection-coated fused silica plate followed by an aluminum filter. In the application …
WebIn contrast to usual statements where high-order harmonic beams are considered as divergent after the generating medium, we show that harmonic beams, generated with a single fundamental beam, can converge after the generating medium and are then focused without any XUV optics. WebApr 3, 2009 · Abstract The investigation of high-order harmonic generation (HHG) of femtosecond laser pulses by means of laser-produced plasmas is surveyed. This kind of harmonic generation is an alternative to the HHG in gases and shows significantly higher conversion efficiency.
