Map of magnetic field around terrawatt laser irradiating magnetic tape

Map of the magnetic field distribution around a terrawatt laser irradiating a magnetic tape. The spatial distribution of magnetic field associated with an intense Laser – matter interaction surviving only for a few 100 ‘s of pico seconds are captured as unusual magnetic field patterns in a magnetic tape. Subsequent mapping of the magnetic field distribution across the tape reveals unusual field profiles.
