“…Models for such processes inherently involve nonperturbative interaction of the intense laser field with matter. High-order harmonics have been produced in monomer gases [1,2], molecules [3], and at solid surfaces [4,5]. Here we report the generation of high-order harmonics of intense laser radiation from atom clusters containing approximately 10 3 atoms, and show that clusters are a unique nonlinear medium with potentially useful properties.…”

“…38.Ph Over the past 30 years, solid-density plasmas driven by intense femtosecond (fs) pulses, so-called plasma mirrors, have been successfully tested as a source of high-order harmonics and attosecond XUV pulses in a number of experiments [1][2][3][4][5][6][7][8][9][10], where the laser intensity typically exceeds a few 10 14 W/cm 2 . Other experiments have shown it is also possible to accelerate energetic electrons from plasma mirrors for intensities above 10 16 W/cm 2 [11][12][13].…”

“…Когерентное излучение третьей гармоники распространяется коллинеарно излучению накачки и, пройдя через полихроматор, регистрируется на многоканальном анализаторе. Такая постановка эксперимента существенно отличается от осуществленных ранее в опытах [95][96][97], в которых исследовалась генерация оптиче ских гармоник в плазме, образованной самими лазерными импульсами в энергией в десятки джоулей, умножение частоты которых и регист рировалось.…”
