Medical infrared laser systems involving a beam delivery cable based on hollow optical fiber are introduced. Two types of the systems are developed to cover a wide range of medical applications: one with a CO2 laser which is mainly for soft tissue ablation and another with an Er:YAG laser for ablation of hard tissue in dental applications. The both systems which have been recently commercialized newly adopted a hollow glass fiber having inner metal and polymer films. Because of the high mechanical and chemical stability flexibility, and the low production cost of the fibers, a reliable and easy-to-handle medical systems are launched at low cost. The components of the systems including the beam delivery cable and distal tips specialized for various medical applications are described in detail.
