Study of Pulsed Laser Damage to Optical Fibers

摘要

This paper describes some observations of pulsed laser damage to optical fibers with emphasis on a damage mode characterized as a linear fracture along the outer core of a fiber. Damage threshold data are presented which illustrate the effects of the focusing lens, end-surface preparation, and type of fiber. An explanation based on fiber-beam misalignment is given and is illustrated by a simple experiment and ray trace. 13 references, 8 figures, 1 table. (ERA citation 10:022405)
