Abstract

This paper is directed at the use of high power continuous wave and repetitive pulsed lasers used in conjunction with fiber optical components. Until very recently, high power lasers have not been an environment that one would have to be concerned with. Given that some investigators are presently looking at high power lasers for transmission in optical fibers, the problem of laser damage and subsequent catastrophic failure are issues that must be addressed. Equations are provided for determining the maximum threshold damage due to coating interfaces and thermal shock in optical fiber materials. Laser damage at interfaces due to thermal shock is one of the major elements to be dealt with. As it turns out, the cladding on the fiber optic becomes an important player in the maximum threshold of the fiber. The outcoupling surface is the most sensitive to laser damage because this component of damage is a manifestation of the electric field and the mechanical bonding of the coatings.
