We have demonstrated the fully spatial coherent 13.9-nm laser with output energy of submicroJoule by means of the double target geometry by using new driver system. The power amplifiers providing tow beams with 10-J energy and picoseconds duration at the repetition rate of 0.1 Hz. The obtained 13.9-nm laser pulse with 10 coherent photons will enable us to make single-shot pump-probe observation of non-periodic ultrafast phenomena.
