%X The MEDICIS facility at CERN aims to produce non-conventional radionuclides towards medical applications. In this work, the first collection of europium-145 (Eu-145) at CERN-MEDICIS is presented, focusing on the development and optimization of a resonance laser ionization scheme to improve isotope extraction efficiency. A two-step ionization scheme was developed and implemented, ensuring compatibility with the available laser infrastructure. The collection campaign in October 2024 successfully delivered Eu-145 for metrology studies, demonstrating the feasibility of laser-enhanced Eu ionization. The results indicate a collection efficiency of 1.85% ± 0.09%, although further development is in progress to optimize the ionization scheme and ion source parameters and operating conditions.
