Femtosecond laser inscription is a unique approach to achieve non-conventional manufacturing of integrated photonic devices such as laser waveguides. Our approach relies on sensitized glasses containing both silver and Ytterbium ions. Laser inscription allows for the 3D-localized production of highly luminescent molecular silver clusters that support waveguiding architectures. We demonstrate efficient energy transfers from silver clusters to Ytterbium, allowing for background-free 3D-localized near-IR emission. Near-IR laser amplification under indirect pumping is demonstrated, depicting the localized creation of a hybrid laser gain medium involving silver clusters and Ytterbium ions as donor/acceptor pairs. Further work targets to demonstrate integrated laser behavior.
We have demonstrated the co-doping of silver ions and Bi3+ in glass allowing creation of 3D structures with tuning luminescence properties from the visible to the near IR with fs DWL. The tunable luminescence arises from the fs laser triggering both the photochemistry of silver ions and the photo-redox reaction of Bi3+ forming low valence Bismuth ions (Bi2+ red emitter and Bi+ near IR emitter). Confocal hyper-spectral lifetime-resolved imaging revealed the shortening of the fluorescence lifetime of silver clusters in the presence of Bismuth revealing the energy transfer mechanism from silver clusters to Bi+.
