摘要：

Measurements of ultrahigh magnetic fields produced during intense laser interaction with solids were presented. Polarization measurements of high-order laser harmonics suggest the existence of magnetic field strengths of 0.7±0.1 GG. It was found that denser regions of the plasma can be probed using higher order harmonics. The technique was found to be useful for the measurements of multi-GG level magnetic fields.
