Femtosecond optical pulses were irradiated into a YBa_2Cu_3O<7-δ> strip-line of 400 μm in width in order to investigate the relationship between the laser beam power profile and the distribution of the optically generated magnetic fluxes. To homogenize the current distribution in the strip-line, a half of the strip-line was patterned into the ordered array structure of holes of 2 μm in diameter at an interval of 4 μm, and several experimental conditions were examined by changing the focal size of the pulsed laser beam at the sample surface. As a result, it was found out that the generated optical magnetic fluxes strongly depend on the power profile of the femtosecond optical pulses, and showed a possibility for the application to a laser beam profiler and the other optical devices.
