Femtosecond laser processing of oxide glasses is a perspective way for the
development of novel glass-based optical materials. Oxide glasses doped
with metal or semiconductor nanoparticles are expected to be especially
promising because their unique properties depending on nanoparticle size may
be combined with their micromodification by ultrafast laser beam fabricating
various 3D structures with controlled optical properties. Laser-irradiated areas
of predetermined geometry containing metal or semiconductor nanoparticles
in a single piece of glass pave the way to improve a lot of photonic devices,
such as ultrafast optical switches, polarization converters, active channel
waveguides and high-density optical memory. Here, we report about one-step
space-selective precipitation of silver or cadmium sulphide nanoparticles
by femtosecond laser pulses inside silicate and phosphate glasses. We
demonstrate that femtosecond laser irradiation of such glasses induces ring-
shaped coloured microdomains which are prone to luminescence, absorption
and homogeneous birefringence. Structure, chemical composition and sizes
of nanoparticles formed in laser-written domains were examined by Raman
spectroscopy, transmission electron microscopy and energy-dispersive X-ray
spectroscopy. Variation of dopant concentration and laser writing conditions
(i.e. pulse repetition rate, number of pulses, pulse duration and energy) are
established to provide an opportunity to control optical and luminescent
properties of the laser-induced domains. Scenario of femtosecond laser-
induced precipitation of silver and cadmium sulphide nanoparticles inside
oxide glasses was proposed.
