Abstract

The use of rare-earth doped optical fibers for amplifier media and specialty lasers has recently attracted considerable attention.¹ Integrated optics offers a natural extension to the concepts of rare-earth doped waveguide technology with the advantage of multiple device fabrication of planar and channel structures on a single substrate. Ion implantation has been used to form a waveguide laser in Nd:YAG.² Silver ion exchange was demonstrated to produce waveguides in lithium-silicate laser glass³ but laser action was not reported.
