  • Medical laser apparatus for delivering high power infrared light
    Patent number: 5349590
    Abstract: A medical laser apparatus which comprises a medical laser and a waveguide is used to deliver infrared energy to a treatment site. The medical laser preferably delivers electromagnetic radiation at a wavelength of about 3.0 microns such as an Er:YAG laser (wavelength of 2.94 microns). The waveguide comprises a fluoride-based guiding structure surrounding an outer protective structure, and is capable of transmitting invisible infrared light at a wavelength of about 3 microns at a power density of at least about 4 kilowatts per square centimeter. The guiding structure has a core and at least one cladding. The protective structure comprises a jacket of material, preferably polyimide, which is substantially impermeable to moisture and has a moisture resistance significantly higher than that of the guiding structure.
