Abstract
A method and apparatus are provided for monitoring an optical signal from a solid state laser. The method includes the steps of providing a planar substrate defined by opposing planar surfaces and a substrate edge that together define a substrate volume that is transparent to an optical signal from the solid state laser, disposing the solid state laser on one of the opposing planar surfaces the planar substrate such that a first portion of the optical signal travels directly through the planar substrate substantially orthogonal to the opposing planar surfaces and a second portion of the optical signal is reflected between the opposing planar surfaces of the planar substrate and passes out of the substrate through the substrate edge, and disposing an optical detector proximate the edge of the planar substrate to detect the second portion of the optical signal.
