Abstract
Systems and methods for dynamically distributing power of a light beam for use in administering light therapy. A laser light beam having a maximum peak power is selectively diffused to distribute the maximum peak power. In at least some implementations, the diffused laser light beam is attenuated across the diffused beam. Having undergone processes of diffusion and attenuation, the laser light beam is then safely used to administer light therapy on a patient. In further implementations, the diffusion includes a defocused diffusion and/or includes a distribution of power rather than an attenuation of power.
