The World Association for Photobiomodulation Therapy (WALT) was formed in 1994 in Barcelona, Spain at the joint Congress of the International Laser Therapy Association (ILTA) and the International Society for Laser Application in Medicine (ISLAM) when these two international groups merged, and WALT became the leading world body for promoting research, education and clinical applications in the field of photobiomodulation with lasers and other light sources.

The multinational membership includes the world's leading experts in all forms of treatment mediated by the photobiomodulating effects of light occurring without thermal effects on irradiated tissue.

PBM2024 is set to become the largest Photobiomodulation conference in our 30-year history, inspiring and connecting the global community of PBM researchers, clinicians, and students. Together, we aim to fulfil the dreams of WALT's founders, making PBM a standard of care for hundreds of diseases and injuries in hospitals, clinics, and homes worldwide.
