We report waveguides in Ni-doped Li2O–Ga2O3–SiO2 (Ni:LGS) glass and glass–ceramic (GC) fabricated
with a femtosecond (fs) laser with repetition rate of 1 kHz. When the glass is annealed to form a GC,
the waveguides are erased. However, in the GC the waveguides are not erased by annealing. In Ni:LGS
GC a 415 nm absorption band was created by fs laser waveguide writing due to the creation of Ni
nanoparticles with an estimated diameter of a few nm. Raman and photoluminescence spectra of the
bulk and waveguide structures were indistinguishable; however, fluorescence decay profiles indicated
more long lifetime components in the waveguide compared to the bulk.
