Prof. Edik Rafailov as Co-Principal Investigator of the COST Action CA23125 - TETRA project, has been awarded a prestigious ECCS-EPSRC grant worth of £0.9 million for groundbreaking biomedical laser research. The project, titled as "Compact High-Power 3 Micrometer Light Source For Biomedical Applications," is a collaborative effort between Aston University (UK) and Stony Brook University (USA). Prof. Rafailov from Aston University serves as Principal Investigator alongside Prof. Leon Shterengas from Stony Brook University, with Dr. Diana Galiakhmetova as Research Staff at Aston University. The project aims to develop a high-power, compact mid-infrared light source operating in the 2.8-3.0 μm wavelength range, specifically targeting the strong water absorption band. The innovative system combines a semiconductor master oscillator with a fluoride fiber power amplifier, designed to deliver controllable pulse parameters (1kHz-1MHz repetition rate, 1-100ns pulse duration) while maintaining clinical viability through compact and affordable configuration. This cutting-edge laser technology will enable effective tissue ablation for various medical procedures, including minimally invasive kidney stone elimination. The system's ability to operate in the strong water absorption band allows for precise shattering of urinary stones, enabling safe removal of fragments through the urinary system. Additionally, the mid-infrared emitter will contribute to developing novel bioprinting techniques, enabling direct 3D bio-tissue printing using advanced lift techniques. The project exemplifies international scientific cooperation, with the US team focusing on high-brightness semiconductor laser development and the UK team developing fiber-based amplification systems and complete system characterization. This significant funding success highlights the continued excellence and impact of TETRA project leadership in advancing photonic technologies for biomedical applications.
