  Since it is possible to form laser pulses with a frequency much larger than
the frequency of visible light, Prof. T.Tajima proposed using such pulse to
accelerate the particles at its injection into the crystal. Here, the wakefield
excitation in the metallic-density plasma and the electron acceleration by
laser pulse are simulated. The accelerating gradient has been ob-tained
approximately 3TV/m. It is shown that, as in ordinary plasma, with time
beam-plasma wakefield acceleration is added to laser wakefield acceleration.
