Abstract

We present characteristics of optical waveguides fabricated in Pr3+ doped ZrF4-BaF2- LaF3-AlF3-NaF (Pr:ZBLAN) glass using simultaneous spatial and temporal focusing (SSTF) of femtosecond laser pulses. Thanks to SSTF, the axial two-photon excitation length is confined to ~20 μm. A primitive example of waveguide shows an NA of ~0.015 and a propagation loss of 0.56dB/cm.
