Shock-wave generation upon axicon focusing of femtosecond laser radiation in transparent dielectrics
Publikováno v:
Journal of Experimental and Theoretical Physics Letters. 80:298-302
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-c

A subterawatt fs laser complex with a power in a pulse P less than or equal to 0.15 TW is constructed. Our experiments show that axicon focusing of such laser light in transparent dielectric leads to formation of a long hollow channel with micron-ord
