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…

Collisional shift and broadening of the transition lines in pionic helium

Boyan Obreshkov, Dimitar Bakalov

We calculate the density shift and broadening of selected dipole transition lines of pionic helium in gaseous helium at low temperatures up to T=12 K and pressure up to a few bar.…
