FLUORESCENT HANDPIECE

摘要

A handpiece can treat biological tissue using electromagnetic radiation, which can be substantially fluorescent light. The handpiece includes a source of electromagnetic radiation and a waveguide. The waveguide is adjacent the source, receives electromagnetic radiation from the source, and delivers the electromagnetic radiation to the biological tissue. The handpiece also includes a system for moving a fluorescent substance through the waveguide. The fluorescent substance is capable of modulating at least one property of the electromagnetic radiation. Industrial, scientific, and other non-therapeutic methods of generating fluorescent light having a desired peak wavelength or wavelengths are also described.
