Generation and registration of high harmonics at surface plasma in coherent wake
emission and relativistic oscillating mirror modes by high-power laser pulses
A universal technique is developed for the detection of high harmonics generated by relativistic and
subrelativistic laser pulses irradiating a solid target. The characteristic features typical of two different
generation methods are analyzed: parametric generation in the mid-IR range and amplification of chirped
pulses in the near-IR range. Experimental spectra of harmonics in the range up to 35 nm were recorded. They
can be used as a source of coherent radiation in the extreme UV region.
