(a) and (b) present the evolution of the z-component of B-field in 3D space. The microtube covers a length of −10 < 𝑧(𝜆) < 10 with the inner and outer radius of 6 and 8 microns. The diffraction stripes in (a) depict the four pumping lasers from x-y sides. The magnetic field inside the microtube increases from 1 to 5 GG within 50 femto-seconds as seen in (b). The gyro motion of the electrons around the central core contributes to the significant amplification.
