| Abstract(in English) | In order to change the output direction of laser light in a small operation space, two types of hollow bent output tips are proposed for medical laser light delivery system. One is the hollow fiber insert-type, which is of the minimum bending radius of 3-5 cm. The other type, based on a fixed-bent pyrex glass tube, is of the minimum bending radius of 2-4 mm. Loss properties for CO_2 laser light are clarified for the tips with various bending angles and radii. A nickel layer is coated on the outside wall of fixed-bent tips so as to increase the mechanical strength and lower the surface temperature. Characteristics of surface temperature distribution and time response were experimentally discussed. |
