摘要：
Improvement in the characteristics of YBa2Cu3O(y) superconducting thin films was performed by a second laser irradiation method. Particles in the laser ablated plume were decomposed and/or excited by the second laser irradiation. By controlling a time delay of the second laser from the ablation laser, ablated particles with average velocities of 1 x 10(6) cm/s and 2 x 10(5) cm/s were irradiated with the second laser. Notable improvement was observed when the slower ablated particles were irradiated with the second laser.
