Laser irradiated Nb3Al superconductors showed critical temperatures TC above 16.0K and subsequent heat-treatment at 750°C enhanced the TC to 18.6K. For laser irradiated and then heat-treated specimens, critical currents IC were little decreased, even over 20T, as compared with specimens which were only heat-treated. A maximum critical current density JC for reacted area of 4.8×104A/cm2 was obtained at 23T and 4.2K. The effects of temperature change and magnetic field direction on IC were also discussed.
