Abstract: It is shown experimentally that the axicon focusing of intense femtosecond laser pulses in transparent dielectrics leads to efficient excitation of shock waves. A method is developed for measuring the dynamics of shock waves, which uses a frequency-chirped probe pulse and has high spatial ($\sim1\,\mu$m) and time ($\sim10\,$ps) resolutions. The initial stage of the evolution of an intense (up to 10 GPa) shock wave is studied by this method.
