Abstract
Interactions of ultrashort, ultrahigh intensity laser pulses with underdense plasmas were studied. The longitudional spatial extent of the pulse duration was close to both the laser focal spot size and the plasma wavelength. Experiments were performed using a multi-terawatt, ultrashort Ti:sapphire laser system delivering 10 Hz pulses at 810 nm. Energy transmission measurement and optical microscopic imaging were used to calculate the evolution from relativistic self-focusing to relativistic filamentation. Results showed that the laser energy transmission becomes larger with increasing laser power.
