Abstract
Terminations for an infrared transmitting optical fiber in laser lower delivery systems are described which enhance the system's transmittance and suppress the probability of laser induced damage within the system. To minimize reflection losses, the input fiber end surface is terminated at a certain angle relative to the fiber's axis and the laser is positioned such that the incident laser beam strikes the input fiber end surface at Brewster's angle. For polarization maintaining fibers, it is recommended that the output fiber end be terminated with or without a solid optical output tip where the angles of the fiber output surface are also at Brewster's angle. Alternative means, which are described, for obtaining reliable delivery of high laser power in laser medical or industrial applications include using hollow waveguides attached to the output fiber end and feedback devices to prevent overheating of the output fiber ends.
