    Abstract: PROBLEM TO BE SOLVED: To make an optical fiber terminal have a low-loss boundary with a light source, detector or another fiber by ablation the terminal of a plastic optical fiber by using an excimer laser. SOLUTION: The terminal of the optical fiber 106 is finished by ablating the terminal of the optical fiber 106 to remove a material containing cracks and interstices. An aperture 102 and lenses 103 and 104 are used to condense the light released by a laser 101 on the optical fiber 106. The light is condensed and is superposed on the optical fiber 106 and is condensed to the center of the optical fiber 106. The cracks and interstices are generated by the first cutting of the terminal of the optical fiber 106 and the oblation is resulted in consequence of the absorption of the UV light from the laser 101. Energy is absorbed only in the initial micron of the terminal surface of the optical fiber 106, by which the induction momentary removal of the material is induced. About one micron of the fiber is removed with each 3 to 5 pulses from the laser.
