ABSTRACT:
A control system for an optical fiber laser power delivery system wherein the system employs a tip assembly for the optical fibers which provide focusing and beam divergence, mechanical protection for the optical fibers, and in addition functions as the source of a condition responsive signal useful in monitoring and controlling the system operation. The tip assembly utilizes a synthetic sapphire lens or window having incident laser radiation and temperature dependent fluorescing property useful in generating a signal utilized in a feedback control system for the laser system. The improved tip assembly accordingly has application as an optical fiber shield as well as a signal source for the control and monitor portion of the laser system.
