Blueshift of high-order harmonic generation in crystalline silicon subjected to intense femtosecond near-infrared laser pulse
Boyan Obreshkov, Tzveta Apostolova
We present the generation of high order harmonics in crystalline silicon subjected to intense near-infrared 30fs laser pulse. The harmonic spectrum extends from the near infrared t…

High harmonic generation from bulk diamond driven by intense femtosecond laser pulse
Tzveta Apostolova, Boyan Obreshkov
We present theoretical results on the high-harmonic generation (HHG) in bulk diamond induced by intense laser pulse of wavelength 800 nm and duration 15 fs. For laser intensity in…
