Detailed introduction

Diffusion Bonded Crystals consist of one laser crystal and one or two undoped material.They’re combined by optical contact method and further bonded under high temperature.Diffusion Bonded Crystals can effectively decrease thermal lensing effect considerably,therefore they are very suitable for high power laser applications.
