Abstract
Huge magnetic fields are predicted1–4 to
exist in the high-density region of
plasmas produced during intense
laser–matter interaction, near the criticaldensity
surface where most laser absorption
occurs, but until now these fields have
never been measured. By using pulses
focused to extreme intensities to investigate
laser–plasma interactions5, we have been
able to record the highest magnetic fields
ever produced in a laboratory – over 340
megagauss – by polarimetry measurements
of self-generated laser harmonics.
