A principle of the laser wakefield particle acceleration has been test
ed by the Nd:glass laser system with the peak power of 30 TW and the p
ulse duration of 1 ps. The particle acceleration up to 18 MeV/c has be
en demonstrated by injecting 1.0 MeV/c electrons emitted from a solid
target by an intense laser impact. The corresponding field gradient ac
hieves 1.7 GeV/m.
